I love the score from Jonny Greenwood. It's moody, it's VERY Greenwood and elevates the dream-like quality of the film. Joaquin Phoenix is the embodiment of a violent lost soul here and I did like the subjective nature of it all. Did he really go through with everything or not? I guess that's up to the viewer.
With references to films like Taxi Driver and Drive the only issue I had with it is I connected more with those films. For me, they are both more satisfying cinematic experiences. Never-the-less, You Were Never Really Here packs both a visceral and understated punch to the gut.
