a little squeamish about dismemberment

We saw Sin City at the Parkway last night. The violence was brutalizing and overwhelming. I've actually needed a little time to get used to it (turns out dismemberment makes me very uncomfortable) before I could start recognizing the artistry involved in the movie. The look of it, the strange black and white digital dimensionality of it is very different and new. I just didn't think the movie was as funny as other people seemed to. Did I mention it was really violent?
