God, man. The robbery going wrong is just so intense and devastating. Fuck, I've seen this movie a million times, and it still punches me in the gut, over and over.
All the strippers just staying cool and quiet when The Driver comes in and starts fucking shit up is such a great scene. Just an odd scary vibe where you know this shit just happens all the time around them.
I think about the scene in the elevator a lot. Where The Driver is with Irene and he knows it's all about to come crashing down, and he just slowly kisses her, the music goes slow, and then he just beats the other person in the elevator to death in front of her.
