Alright I read the Comicbook once a long time ago. I forgot an awful lot of the sub points (Like the little tryst in Archie, was that even in the comicbook?) And I am not sure I remember all of the gratuitous sex, and nudity. But I thought it was better than 300 and Sin City.
Still if you plan on going to see this be forewarned, there is A LOT of violence and Blood, and sex. Also there are some characters that are suggesting that God exists and some that deny He exists.
