Superman 2 when it was taken out of Donner's hands yo. Sure, his version used fucking time travel again, but that wasn't as bad as the random ass powers displayed at the end. (throwing his S, lol...)
We probably mostly remember Superman 2 as the best movie, too.
superman 2 and 3, don't hold up.
I can tell you as a kid, I loved both. Loved Pryor, everything. The S shield was silly, but so what? It never even occurred to me that Zod, etc might have died falling into the pit. that is the kind of thing adults see and question.
so there is a truth there. Making a movie kids enjoy, and one adults do often don't entirely line up. its BEST when they both do. Starwars holds up. Raiders holds up. temple of doom does not.
superman 1 holds up. Superman 2 not so much. Most of it does. But not all of it. The whole director swap, plot changes etc are kindof noticeable in hindsight, esp as an adult. And as much as any of us WANT to say, zomg Donner's vision and Donner cut!.. there is no way you can justify rewinding time AGAIN, and rape kiss. Other then, thats the best part of Superman Returns. The reason Lois doesn't know her kid belongs to Superman, is he had sex with her before the end of Superman 2. got her pregnant, never thought to check, then erased her memory of it at the end of superman 2. and he left for Krypton right after, before she started showing.
it was silly enough the first time, but completely undoing everything that happened in the movie is terrible catharsis.
