I see nothing wrong with the Donner cut's ending, considering that it was more or less what was in the works at the time the Salkinds shitecanned Donner, wasn't it?
It was a bad idea back then, too. I only barely forgive them for using it in the 1st movie because...
1.) He only turns things back a few minutes, rather than erasing the entire movie.
2.) There's a certain implication that he probably wouldn't be able to do it again because he was only able to summon the strength to do it this time due to the uncontrollable rage at Lois Lane's death.
