Saw this last night. Two things. First, a gaping plot hole kind of ruined it for me. I ain't gonna spoil it, but let's just say the whole second half of the movie could have been completely cut based on a logical decision in the best interests of the decision maker. Second, they destroyed more of NYC/Metropolis (whatever) than Iron Man and Avengers put together. To top that, Hollywood will have to create two gigantic colossi that duke it out all across America, stomping on every city large enough to have public transportation. My second favorite part was the first 20 minutes, up until they sent Zod's crew up to exile in those space penis-craft. My first favorite part was the Carl's Jr. commercials on TV.
Other than that, it was a decent popcorn flick.
