For the record I do like Superman II: The Richard Donner Cut but I still prefer the Richard Lester one. It had some moments superior to Lester's like the appearence of Jor-El and the proper explaination of how Clark got his powers back. In the Lester one we just see him hold the crystal and that's it. Also I didn't like the ending to the Donner one which had Supes turn back time again and literally go back to the beginning of the movie. In the first he just went back a few seconds, which he shouldn't have anyway but going back to the very beginning is kind of a cheat if you ask me. Also like in the Lester one at the end he confronts that bully who beat him up earlier, but if Supes turned back time then the bully would not have remembered him. Also in the Lester version Clark and Lois slept together after he gave away his powers but in Donner's they sleep together before he gives them away, which brings me to the existence of their son in Superman Returns. When you think about it Superman Returns takes place five years after the Richard Lester version of Superman II and not the Donner Cut. Some people didn't think it made sense that the kid had powers when his father was powerless when he and Lois slept together, but here's my theory which other people probably know. General Zod tells Superman to enter the machine which has revealed to changed outside and has Zod and his minions lose their powers and I'm assume it gave powers to the kid who was inside Lois. Also in the Donner Cut Superman destroys the fortress of solitude which was in Superman Returns so that proves that both those films don't co-exist with each other, though who's to say that the fortress actually returns when he actually turns back time but Lois wouldn't be pregnant. Also in my opinion and possibly others there are three seperate Superman movie universes which revolve around the first. One universe features just the first four, the second features just the first two and Returns and the third one features the first one, the Richard Donner cut of the second one and possibly the third one but not the fourth one because the fortress of solitude is in that one.
