I saw Sin City on Friday, and it's a work of art. Visually, the movie is simply stunning. It's worth seeing in the theatre just for the visuals. Be forewarned, the movie is pretty violent, with enough violent acts done to people's genitals to keep your legs crossed throughout the film. In any case, Mickey Rourke is outstanding in the film, though Clive Owen and Bruce Willis aren't bad either. Check out Roger Ebert's review, and if you're still interested, go watch it, you won't be disappointed.
