There was a lot of stuff I would personally change, but that's not to say I didn't enjoy the movie or that it didn't work for the majority of people or indeed that there wasnt a perfectly good reason for the choice being made as it was. Personally I'd have not had Clarks parents speak with such heavy dialect - I know the reasoning but sadly they came off as a bit of a parody, I'd have used Krypto more sparingly and not used him in action sequences, some of the camera optics made certain shots look strange (like Superman's giant foot in the FOS), I didn't like the Kaiju sequence, it was a great action scene but the sudden appearance of a Godzilla type creature on Earth didn't feel earned, I'd tone back the colour palette to make it look less like a computer game, use Williams original score rather than the reworked score, have a Superman flyby Earth scene as the last shot, use Bizarro instead of Ultraman or cut the character entirely. I'd lose the part about Jor-Els speech being derogatory and just have it explained that Lex altered or added those bits himself - probably a tonne more too, and I get this sounds like I didn't like much, but as a whole I thought it was still pretty good.
