As already mentioned if you are a Superman fan you have to watch The Donner Cut. It has alot of history ( not a typical director cut) the movie is still not perfect it gives a better view of what the movie should have been. Biggest criminal change is Superman doesn't ask Zod to "step outside". And if you watch forgive the ending, they hadn't quite worked it out yet. Plus it has Marlon Brando which works sooo much better.
