Crash is I think, so far, my favorite erotic film. I find the combination between the eroticism shown through the character's fetish for car crashes, and the weirdness throughout thoroughly entertaining and interesting. All the characters are very well contoured, like sex on legs - driven, completely by their fetish and sexual fantasies. It's a very honest, bizarre, and why not - creative movie, and certainly not for everyone.
That's precisely what makes it good in my book. Also, James Spader, man, he's made for movies with sexual content (remember Secretary?). He just exudes perversion in the most seductive manner, if that even makes sense. Holly Hunter is, as usual fantastic. Just that attitude she always has, despite having to play a certain character - just always gets me. Elias Koteas as Vaugh was pretty great, his character made me feel the passion he had for his fetish.
