Went yesterday and I really enjoyed it as well. I really enjoyed it pretty much from beginning to end, and hope that it springboards to a united DCU ala the Marvel movie world. I have to admit during the big Metropolis battle scenes thinking "how cool would it be if Batman came flying in in the batwing and started firing on that thing too". The fact that this could open the door to that type of thing eventually is exciting. I can see the point about all the building smashing and stuff, it almost did get overdone at some point, but overall it was pretty cool. You could definitely tell it was a bit of a reaction to Superman Returns where everyone was saying "HIT SOMETHING!!!", because there was plenty of it this time around. Overall, I really liked the movie though - and the cast in general. I think I enjoyed this more than Iron Man 3 even, and this from someone who is more of a Marvel guy overall. Our daughter loved it too, although one of her first comments coming out of the theater was "I was hoping Supergirl would show up"

. I do hope that this success opens the door to at least a Wonder Woman movie being made, because I know my daughter is just aching to see a female superhero movie - or at least appearances by Supergirl, Batgirl, WW, She Hulk, new Invisible Woman, etc. Oh, and she wants a Teen Titans movie

. Anyways, Man of Steel gets a thumbs up from me.
On the more spoilery side...
I read an interesting blog from Mark Waid (big comic writer and Supes fan, and author of Birthright which a lot of Man of Steel was pulled from), and he comments about all the collateral damage, in addition to the whole Zod thing at the end. It is an interesting read here:
http://thrillbent.com/blog/man-of-steel-since-you-asked/I admit to thinking about that a little bit too, and I didn't read this blog entry until after I saw the movie. I kept thinking about how Superman didn't even seem to be avoiding all the building smashing and how many people were probably dying in those buildings. But, at the same time, I can see how this approach is a little more "realistic", since if something like this was actually happening - unfortunately, people were going to die. Anyways, it is a good read either way.
