I liked the movie, but that is about it.
I thought the pacing was off. It kept getting better towards the end of the movie but in the beginning I was confused at was what happening all the time, because nothing was really given the screen time that it needed. How the movie just went from the spaceship crashing down into the earth to Clark doing some shit on a boat was so weird.
The dialogue was pretty bad, but hey, what do you expect. Russell Crowe's lines were epic, but then again they were taking one on one from a Superman comic so whatevs. Michael Shannon did a pretty good job at being angry but he doesn't seem like a nemesis guy to me. Probably have to wait for Lexy Lex in the sequel for that.
My main gripe with the movie is that it was all so fucking serious. Jesus Christ Clark, can you for a moment not look so constipated. I know you are destroying half of New York and killing millions, which doesn't seem like a good thing, but you don't have to be so sad about it. Lighten up for fucks sake. The 'It gets worse after the first kiss' line made me realize that this was probably one of the two jokes in the movie. In the trailer the S-joke already seemed off and in the context of the entire 2.5 hours it seemed even weirder. I like my fun....
Overall, well made movie, loved the 3D mercury visual things, great interpretation of Superman as a character, but the contrast between the serious tone and the ridiculous dialogue and action was too much for me.
