When watching a film over and over again it's easy to take it for granted. I've seen this one so many times at this point that I might underestimate the beat-by-beat greatness. Kubricks visual style is also just being formed in this one with a couple of hints of his deterministic directorial eye, best shown in a few one point compositions. But thematically this might be Kubrick at his most fascinating and interesting.
And the ending is still the best…
