I would KILL to have a Super Smash Bros. film! The best way to start is to just have every film focus on their own story, and once you've established the characters you want, THEN you do a Smah film! (and then have Sonic save everyone at the end, just like Smash Brawl)
To be fair, most deaths are "unforseen" just in general. Part 1 was honestly a bit better imo. None of this really changes my mind on this is all just being a lot of coincidences. Our minds like to make patterns cause we fear the unknown, the random.
