Highlander 2 needed a dishonorable mention. It was so bad I wasn't sure whoever directed it had seen the first movie.

At least “Plan 9…” makes for a fun bad movie night. Ed Wood may have lacked actual skill in the craft, but you can’t deny he had heart and threw himself into each piece of crap he made

That Godzilla movie is the main reason am the Godzilla fan now. I loved it as a kid.

I knew Battlefield Earth took the number 1 spot on this list!

I like Godzilla 1998...

I actually went to the movies to see Godzilla 3 different times. And its definitely in the cult status nowadays.

Cats should be on this list. Wait, Cats isn't Sci-Fi ... I don't care.

In my opinion, Moonfall is a fun film! It is obviously not an award winning film, but it’s a fun film!

I really liked the premises of Jupiter ascending. That an alien civilization ”plants” and ”harvests” planets with lifeforms they’ve created. It was kind of cool to see them walking around vast empty cities. Then they tried and failed to make a good story out of it.

I actually liked JUPITER ASCENDING, GODZILLA, and the honorable mention of AFTER EARTH. Just not that much.

The Last Jedi is missing from this list.

The second pacific rim movie (oh lord, they made TWO?!) was so hilariously bad that I doubt anyone has seen it unless they also had massive insomnia at 3am staying at some random hotel in the middle of nowhere with only four channels. Without knowing what movie it was at first, I thought it might be satire.... but it was not.

Roland Emmerich proved that he has nothing to prove

Kyle Broflovski: They're not gonna show that stupid-ass Godzilla movie again, are they?

Oh, my God! My brother gave me the 1998 Godzilla movie *twice* for Christmas! First on VHS in 1998 (traded it for the Sailor Moon Doom Tree series) and again in 2005 on DVD (traded this for a different DVD). 🤮

I actually really enjoyed Chaos Walking, the idea behind the film is good, the execution might not have been the best but I don't think it deserve to be in "WORST Sci-Fi Movies" category

There is nothing wrong with the day after tomorrow,Godzilla 1998 & Planet of the Apes 2001.

I come to these “worst” lists for suggestions of things to watch and I’m never let down. It’s like critics don’t even watch the actual movies lmao

I fell asleep during "Star Trek V." Since that's the one Roddenberry apparently said you can skip, I never went back and just moved on to "The Undiscovered Country."

_Godzilla_ (1998) felt like a fever dream I wanted to wake up from.

Roger Ebert's review of the 1998 Godzilla version said that they showed it as the closing movie at the Cannes festival for the same reason they put the horses at the end of a parade!

That crappy time movie with Timberlake.

Oof, we never talk about Battlefield Earth 😭💀

Top 3 worst really needs to be Disney's Palpatine Trilogy.

The most recent Star Wars movie needs to be on this list.

Having loved the Alien franchise up to pts three or four, I was paralysed at Prometheus. Those geeks go out on an alien planet without protective gear got me. Sure, the computer said the atmosphere for good for humans, but what about the germs the astronauts let loose on the planet?

Bruh, how did Robocop 3 not make this list? Seriously, that movie makes Chaos Walking look like a masterpiece. 😆

The day after tomorrow and 2012 deserve to be considered for this list?! Seriously? How they gave the audience everything we'd want in an epic disaster movie. Pfft lame call

0:20: 🚀 Disastrous sci-fi film Moonfall fails with convoluted plot, alien invasion, and laughable science accuracy. 2:32: 💥 Sci-Fi movie industry struggles with reboots, disappointing returns, and canceled sequels. 4:42: 💥 Disastrous sci-fi films with poor writing and acting receive scathing reviews, even from the producer. 7:04: 🎥 Disastrous science fiction movies with massive budget failures and critical backlash. 10:04: 💥 Crash landing on a disastrous planet, a sci-fi film starring John Travolta as an alien leader receives harsh criticism. Timestamps by Tammy AI

I loved Moonfall, me and the wife knew exactly what is was, it wasn't made to win any awards, but damned if we didn't have fun watching it. Jupiter Ascending the same thing, just a fun movie to enjoy on a saturday night with the family.

Rebel Moon Part 1 should be on this list. That is the most bland boring generic scifi I've ever seen

You can throw Star Wars Episodes 7,8, and 9 in there.

You forgot the star wars prequels, sequels, & Solo movie. Lightyear Strange World Terminator Salvation & Dark Fate Signs

Battlefield Earth got a bad rap, people were poised to judge it as bad before they even saw it, it was pretty good science fiction. One critic of fame haughtily laughed and asked "When has an alien ever acted like that? Ha-ha". I was left with the question how does an alien act? 🤔 I then realized it was prejudice I was dealing with. (I did have a problem with primitive humans mastering Jump Jets so quickly but it was fiction.) 🤷‍♂

Piranha II: The Spawning? I loved that movie. "It's the guests, sir. The fist are eating the guests..." Pure. Cinematic. Gold.

The Star Wars sequel trilogy should be on here

I knew Battlefield Earth would be number one. But it’s among my favorite “so bad it’s good” movies lol

Hey, Moonfall, Terminator Genesis, and Godzilla were not the worst movies ever. Not great? Yes. Worst ever? That’s a bit harsh. Doesn’t Batman and Robin count as a Sci Fi movie? Mortal Kombat Armageddon? Last Airbender? Dragonball? Catwoman? Jaws the revenge?

"Chaos Walking" was meant to be a start to a trilogy but the YA novel to movie genre was dying by the time it made it to screen. It's hard enough to follow the story in the books but it doesn't translate to screen, especially with studio interferance.

STAR TREK V got some major things wrong, but it was still better than the JJ Abrams trilogy. Unfair to call AFTER EARTH a 'Smith Family Outing'; there were roles that could have been taken by Jada P and Willow. Casting Jaden made a lot of sense: It was quicker that trying to find an unrelated young actor who looked enough like Will Smith (who'd have the ears?) What about INTERSTELLAR? Silly premise relying on pretty incredible coincidences, weak characters, scientifically inept even in the non-astronomical stuff (how heavy is a wave as high as a mountain going to be, and what will be left if it lands on you?), and the heroic achievement is based on appalling morality - better to find Planet B that save Planet A (and most of its population)

Jupiter Ascending is alot to take in at first but I really got into it as a B-movie sc fi that reminded of Flash Gordon. After Earth, is so underrated, It probably would have done better during the days of ID4 and Men in Black films.

I was actually able to enjoy AFTER EARTH in my country The Portuguese dub was able to mask Will and Jaden's bad acting The movie could use a remake, because it has an interesting worldbuilding

my worst sci-fi move was Dune from 1984, but the overall most horrible movie i still have nightmares about is Angel from 1993, it was so bad i wanted to scratch my eyes out.

I'll be honest.. I was a little kid when I saw that Godzilla movie and it was bangin... I didn't knew the origin and stuff... For me it's just a giant dinosaur... But later when I saw the real Godzilla and stuff.. knowing that.. yes that one sucked... But for a geek kid... That was a cool movie

You missed out on Santa Claus Conquers the Martians. My dad likes a lot of low budget movies like that and even he thought this one was bad.

Thank you. My PTSD has reemerged

Battlefield Earth is perhaps Hollywood’s biggest BRUH moment

In Godzilla: Final Wars, Japanese Godzilla got a chance to fight American Godzilla and won without breaking a sweat. Great scene.

I agree with Battlefield Earth, Future World, After Earth, Mac and Me, Ballistic, Plan 9 From Outer Space, Pluto Nash, and Piranha II: The Spawning, as they are the worst. But Chaos Walking, Godzilla 1998, Terminator Genisys, Jupiter Ascending, Moonfall, Star Trek V: The Final Frontier, and Planet of the Apes 2001 are more like mediocre or lame or meh but not the wrost since there are many bad and very aweful sci fi films than them that you didn't mention like: 2177: The San Francisco Love Hacker Crimes Birdemic 3: Sea Eagle Dune World Extraction Point Monster: The Prehistoric Project Hornet 2018 Konga TNT Virus Shark. And many others.

Wachowski's have made exactly one good movie, so its no surprise anything they touch is meh at best.

Rebel Moon deserved a mention on here, utterly derivative nonsense that just straight ripped off other and better sci-fi franchises, with awful paper thin characters that had no depth whatsoever

I was entertained by Jupiter Ascending. I attribute that to: Being in the mood for some theater-sized eye candy, Knowing enough SF to (eventually) piece the plot together, Getting a feeling that the over-the-top acting reminded me of Flash Gordon (OG), And taking a few hits of Blue Dream before the movie. Mmmm, popcorn

The Day After Tomorrow deserves a consideration for this list? Hell no.

"I don't think I can shake him!" Why not FLY HIGHER? Yeesh.

Let’s get honest for a moment!!! If any apocalypse happens today having to do with science; Mr.NDT would likely by a good percentage predict wrong concerning the science based event. He is speaking on moonfall but how greatly did he predict Covid 19 a few years ago 👨🏾‍💼🧋

The last three Star Wars movies are not on this list?

@10:21, did you say "Revolta"? 😜and not that it would have helped, but "Battlefield Earth" reportedly only covered the first half of the book. Other mentions: Uwe Boll's filmography? 😜 The 2017 "Mummy"? "Independence Day: Resurgence"?

Santa Clause Vs. The Martians gets my vote!

Just this morning when i was thinking about the new dune film i was like "since WM already did the list of best sci-fy movies what if before they do the list of worst?"

Good vid actually like a few of the movies on the list. They didn't cancel a sequel to Battlefield Earth it would have been a continuation the first movie was only half the book.

Now, Battlefield Earth was a pain in the neck, but the question lies on this: Will John Travolta give himself another chance to be in the sci-fi genre?

I don’t see the Star Wars sequels there

The worst SF movies on this list are the unexpected RU-vid ads. Regardless, I agree with this list, and it could be much longer too.

Sci fi movies have complications in making films especially big budget movies. Mac and Me, Delgo, Independence Day 2, Supernova even Ghosts of Mars are really bad movies to rewatch even they tried to make it good.

"Cabin Fever", with that kid from Boy Meets World, was two hours of my life that I'll never get back, and I'm that much dumber for having watched it.

Number 1!!!! Star Wars Episode 7, 8 and 9

You forgot "Star Crash"! Even at an age of 14 years I realized that this movie is BS and that I got screwed when I paid to watch it in the cinema. I was too giddy, after "Star Wars" completetly changed my understanding of sci-fi movies, to notice that "Star Crash" just tried to surf in the wake of "Star Wars" until it was too late. Real bad acting, bad modelling, bad stop-motion, ... it takes less time to say what's good about this movie: Nothing! Funny enough, it only took the first large spaceship to make it's flyby in front of the camera, when I knew this movie is trash: Seeing the cockpit of the "Space 1999" Eagle Transporter from the AIRFIX model glued prominently to the hull.

I love Battlefield Earth. Never understood the hate.

Chaos walking was actually a good movie like others are saying here. Being released at the height of covid and the rumors about Daisy being difficult to work with played a part

"Benign AI"... LOL! You don't like Godzilla? You're nuts! I love it!

"I love dogs" lol 😆 😂😂

Thank you for the update, WatchMojo..!! When I first read the title of this video, the first movie that came to my mind was "Battlefield Earth (2000)".

Tom holland has the curse of being Spider-Man and not being Tom holland. Bro can probably do a movie or show he has passion for but no one will watch it because he’s not Spider-Man.

After reading the comments I see I'm not the only one who liked Godzilla :) Also, I don't think Planet of the Apes was top 10 worst. I'm sure there are some 'drive-in' movies out there that no one remembers that are much worse.

Earth's moon isn't going to hit the Earth,it's actually being pushed outward. No Majora's Mask future for us.

Another dishonorable mention: Tomorrowland, with Clooney and Laurie

5:01 Helicopters can't fly up in Godzilla 1998.

We have bootleg, unofficial MST-style roasting of Star Trek: The Search for God (unofficial title in our house like the other one is Star Trek: Save the Whales), and it is absolutely hilarious.

Before Battlefield Earth was released , George Lucas got to preview it . George thought the movie would be a big hit .

How bad were the 8 plans before if this was the best?😊

After Earth at least has some interesting speculative zoology / ecology. It's compromised by the stiff acting Shyamalan apparently demands from performers, but it's an entertaining watch.

I read the Chaos Walking books: The Knife of Never Letting Go, The Ask and The Answer, and Monsters of Men. It was made into one movie, and so much was cut out. I liked the cast, and it had so much potential, but it was a giant dud at the end. It should’ve been made into a trilogy, like the books. It would’ve been so much better.

I will always maintain that you can have fun with _Battlefield Earth_ if you go in with the right MST3K/Rifftrax-esque-mindset (and probably some Alcohol in your system). Thats more than I can say for some others of this list which I can't even watch to make fun of.

I remember watching a really boring Sci FI movie that I can't remember the name of. I had to forewind through it. It's just a muddled collection of short stories. Pretty much all the characters do is talk and talk. I want to see something else happen. If I wanted to see people talk I would watch 12 Angry Men. The futuristic tech looks cool but it lacks an interesting story. Only the last story was remotely interesting but it ended before much has happened. That was the worst sci fi movie I've seen.

Some say that Godzilla killed Maria Pitillo's career

Is Emerich not also responsible for the Independence Day movies? The guy needs to have his creative wings clipped big time. And it's been ages, so somebody remind me - what's the sci-fi element in Balistic that puts it on this list?!

_Jupiter Ascending_ is a movie that needs to be watched multiple times to fully understand it. It wasn't bad but it wasn't meant to be "light fare".

8:33 "Here're few dishonourable mentions" 😂

moonfall was so outrageously stupid it was kinda fun

I went to see Battlefield Earth on the big screen. I tried to like it for about 20 minutes and I just laughed at the rest because that was better than crying over my wasted money!! I did enjoy the Godzilla movie as a guilty pleasure and I thought Jupiter Ascending was okay, but Battlefield Earth omg it would be almost impossible to make a worst movie!!!!

Hey now, Godzilla was a good movie. Jupiter Ascending was a lot of fun, and Ballistic was good as well.

I’m broke right now, so I can’t pay for premium like I normally do, but they amount of ads on this channel is insane. I waited, and I counted 9:28 minutes of advertising! This is a 11:28 video. I know it’s not your fault, Watchmojo, but that’s absurd. Shame on you RU-vid.

I never saw Godzilla(1998)as a sci-fi movie. To me its an action adventure monster movie

7:41 again really this was good

This list reminds me how easy it is for a child to find enjoyment

Even.L Ron would walk out.of Battlefied Earth 😮

I feel feel like so many people(like me) as soon as we saw the title said out loud, "Battlefield Earth" and we were right!

Only one good thing about Future World from 2018 was Milla Jovovich. The only highlight of the whole movie.
