I've just seen the movie and I found it terribly powerful, one of the greatest compositions I've seen. Crash combines fast action, shocking cinematography, great performances, beautiful music, and a very particular kind of suspense, in which you know exactly what's happening but can't help hold your breath anyway. It's fascinating how the movie works as a fantastic essay about contact and communication, and how it conveys its meaning perfectly. The way the film depicts the lack of identity of the characters, and uses cars as the thread to connect the stories to show without flaws its main theme is amazing. Absolutely worth seeing. One of the best essays about racism and duality I've ever watched.
