The performances in the movie were great as well. I believe my favorite male character was Marv, played by Micky Rourke, and my favorite female character was definitely Miho, played by Devon Aoki. It seems that everyone and their dog was either in this movie, or lent some of their talents to it, and it shows.
I would definitely suggest that you see this in the theatre the very first time, because it will NEVER have the same impact on your TV at home as it does on a 30-foot screen in a dark theatre. I was actually able to note a few times where the digital cameras were able to outperform anything film could do.
A lot of violence in this movie, although most of it is either totally cartoon-style, or off camera, and some gore as well... A good amount of nudity in the film, ALL of it on camera, so you'll probably want to leave the kiddies at home.
All in all, one of the best movies I have seen in a long time, and I'll probably go see it again while it's in the theatres, so that my fiancé can enjoy it as well...
