I watched a movie called Crash yesterday. It's been around a few years but I'd never given it a second glance. Sat down to watch something random while eating some food and ended up mesmerised for nearly two hours. I won't go into any real details as I think watching it without expectations or pre-set ideas will make it more enjoyable.
It doesn't re-invent the wheel but it's just masterfully told.
I'm assuming you mean the Paul Haggis Oscar-winning one and not the David Cronenberg weird-as-fcuk one?
