I've read many of the negative reviews and their gripes are pre-conceived notions for they feel Superman should be.
They don't know the comics, they don't know really anything beyond Donner.
Many yes have criticized pacing issues and there are some here and there but I can point out every single superhero film (including Donner's Superman and TDK) which have pacing issues.
Superhero films in general I think always have pacing issues and to me the pacing and a few of the scenes in the film didn't do anything that detracted me from the picture like others have. I just take it in stride - do I wish they totally ironed those pieces out, sure but overall, I'm SO happy with this film.
I come with the approach here that despite being heavily critical of the marketing - overall I really wanted this film to work given the prior aborted attempts. Had ANY of those other films come around, I guarantee they would have sat in the low 30% range.
This film to me is just so good, seeing it finally, seeing Superman updated, kicking ass and really being a hero. This is a great start for hopefully a great franchise and I feel the sequel will be even ballsier and even more adventurous and break new ground and be bolder with better story telling. That said, this film just works on all the levels it needs to. It's not a perfectly pressed shirt, but it's pretty much there. Just seeing Superman finally PUNCHING the **** out of others, WOW, seeing the range of emotion and seeing Cavill - he's excellent in this. Seriously, the earnestness to the rage. He has it all.
Donner's stuff was terrific and for me yes still holds up but I'm so glad they went in a different direction and really pushed things. The SFX and action are by far the best you will see in a superhero film and I'm so proud of what they've done. It's just such a blast.
