The dialogue in Z although campier has so much more gravitas it's unreal, Trunks talks about already having seen that power "all his life" and not allowing it to happen again even if it means "taking [Vegeta] down" as opposed to simply "fighting" him. And it's not even just the dialogue, but the VA's performances as well. An example that comes to mind is Vegeta's monologue after Cell is defeated, where he ends it by poignantly saying "I am no warrior, and I will never fight again". Kai omits the former half of that and Christopher Sabat delivers the line rather flippantly which feels totally out of place considering what just happened to his pride and his son. I don't understand why the Kai script rewrite couldn't have striven to preserve the profound moments Z did have.
Goku knew he could kill two birds with one stone, he wanted the battle experience from cell & could help gohan ascend to the next Level, challenging the rest of the saiyans to ascend as well.
Goku have the most respect from me for this sad yet amazing moment. I am starting to wonder something that just bugged my mind: Could that if Vegeta knew Final Explosion and he used, would the explosion cancel the self-destruct and stop Cell or would Cell explode and Final Explosion was used in vain?
Toriyama needed to have Cell back at full strength because its what's best for the story. It was more satisfying that Gohan beat Cell at his best. He was undisputedly stronger. It was in-character for Goku to make that decision, it is what it is
Gokou had to much faith in Gohan’s rage, though it paid off. But Gohan’s dislike of killing (despite the previous arcs) and arrogance was not something Gokou expected to happen. In the wise words of Kreia from Star Wars: Knights of the Old Republic 2 R.P.G Kreia: Plans are a fragile thing that life often dashes expectations to the ground.
It’s a shame that many people don’t realize that if Goku had not given a senzu bean to Cell they would have all died, it was dumb without a doubt but it was also the reason why they able to live
"I love the type of woman that will actually just kill me. You know, when I left the house today I was thinking "Damn," "I really hope some hot chick paints my brians all over some fucking hallway." And here we are. I mean really , just absolutely destroy me. I'm talkin' full on, watermelon-in-the-thighs level carnage. And I want it to scare the shit outta me. I mean I hope I piss myself. I hope I piss myself and you call me your little "peepee pisspiss boy." I want you to fuck me up. I mean I want you to make me your bitch. Your little peepee-piss-myself-bitch. I want it to get embarrassing. I mean like... wierdly embarrassing Unsanitary, too. We should be entirely different people, by the end of the first eight hours. Do you understand what I'm trying to say here? I mean, I'm a real freak. I'm not normal. Ma'am... Please... You have to crush me."
