Very good, though it's a bit slow until you get into the second half (really picks up during the scene of Nite Owl and Silk Specter at the prison). Rorschach kicked bellybutton and was probably the best part of the movie. Silk Specter was hot (there wasn't as much female nudity, but what there was was DAMMED worth it
). I'm kind of pissed with the critics COMPLAINING about the reverence and loyalty to the source material. Hollywood changes and screws up so many other properties (*cough* Star Trek *cough*) it's refreshing to see them actually make an effort to stay close.
I've never read the original comic, but it's DEFINITELY different from any other superhero movie out there. Closest comparison I can think of is start with the melancholy of Dark Knight and multiply it by about 1000. This movie is BLEAK (Dark Knight depressed me as it is....) I was stunned that there were people who had KIDS with them, tho. Aside from the nudity, there's quite a bit of blood and gore in this. Keep the kids at home.
