I've watched it repeatedly as it's currently on NetFlix instant streaming.
Definitely enjoyed it more after a few times around. Could have been better with more actual driving and car chases...
The soundtrack, art direction, and overall atmosphere was great. Very 80's.
The casting was fantastic. Every actor performed their roll convincingly.
The writing was good. Not stellar... but the characters had some depth and the story was intriguing.
The direction was... ok. Some awkward silence moments, while very good to showcase emotional turmoil and really soak up the tragedy and drama, tended to drag on a little too long.
I think the highlight, really, was Ryan Gosling's character, and his performance. The Driver was a very dark, 80's style hero. His brutality and "get it done, whatever the cost" style was refreshing in the age of political correctness...
