I went to the midnight show last night. The movie is... amazing. It's been about 13 or 14 years since read the novel, so I couldn't recognize any changes, but the film definitely does it justice. And it's so nice to see a comic book movie that fully embraces an R rating. Haven't seen many do that since From Hell.
I wouldn't say amazing myself, but I thought it was pretty good. The other 4 I was with didn't care for it, but what do they know?
I think the big blue male "appendage" was a bit much at times, and there was some violence that really was just a *bit* more than necessary (the scene with the killer of the little girl, for instance), but overall I really enjoyed it.
And I really want to encourage people to leave their little kids at home when going to "adult" films (in this case, an R rated movie with a lot of violence, an anatomically correct blue man that can be 100-ft tall, a semi-long sex scene (not that I am complaining, mind you), and lots of blood and exploding bodies). Really. You are screwing up your kids for the cost of an occasional sitter. Knock it off.
