Sure it has some WTF moments where the scenes sort of jump around and they could've done a better job with some of the sequences, but overall I enjoyed it. i have some nitpicks on the story, but i'll wait for some more to see it before we discuss.
I was just going to say that the few reviews i've read this afternoon seem to have wanted a Marvel-esque movie. It's not fair to expect that. Part of me wonders if critics are just piling on what the first few had written.
