Although I also don't like the end of Superman turning back time again!
Yeah, this bothered me in the Donner cut too. It makes me wonder what we are missing from the shooting script. In I, he turns the world back because he's depressed over Lois dying. In this version, there's no good reason for it, other than the novelty of seeing Perry's toothpaste in reverse. But, they say that this movie is the closest they can come to Donner's original vision, so, what are we still missing?
