David Goyer needs to have his screenplay licence take away. Good lord, the dialogue in Man of Steel was awful. Goyer is a wonderful story teller, and he pieced together the Batman trilogy with perfection, but his talent falls apart when he enters the screenplay room. His weakness for dialogue just ruined this movie for me. 2+ hours of mini-monologues, with not a single conversation feeling fluid or natural. For a superhero all about humanity, nobody felt human. Everyone might as well been the same kryptonian baddie.
I also cringed at the scientific ambiguity of most of the scenes needing some sort of resolution. "Hm...maybe if we take this alien ship, and crash it into that alien ship...yeah, that should cause a mini black hole just big enough to get rid of all of our problems." Seems legit. Also, why the fuck would you put a command access point in the prison room holding Lois Lane? Better question, the fuck was she doing on the ship in the first place? "Excuse me miss, David Goyer *cough* General Zod demands your presence aboard the Enterprise to be used as a plot device *cough* to fuck you *cough* to probe you for information."
Pros of the movie: action scenes were amazing. The new Superman suit is kickass. Most of the important actors were awesome. Clark Kent actually looked ripped as hell, which is something I thought they failed with, with almost all the former Supermans. Lord knows Tom Welling isn't a genetic jackhammer. The intro scenes with Krypton were new and refreshing.
