One thing I noticed when rewatching this film was the absense.

In the initial robbery scene with Oscar Isaac there is the absense of a soundtrack, something that a lot of films would need and would perhaps be vital to the scene. But it had no music, just raw sounds. It felt that much more intense.

Another thing of absense was the action cut, during the shoot out with Christina Hendricks, it would almost seem integral to action scenes to include lots of fast cuts to invoke excitement and action; however, a lot of it is even in slow motion.

I think that's bold and beautiful
