THE KILLING is awesome. It's hard to think of a better example of a young filmmaker improving his craft from one film to the next better than with Stanley Kubrick and the rough around the edges, KILLER'S KISS in 1955 to the incredible THE KILLING only one year later. Memorable characters that are all bitter and hard-boiled as fook, a quick pace, the acting by the entire cast is great, awesome story, a few shocking moments...but I think the two things THE KILLING is remembered for the most is its photography and non-linear storytelling. Both have been copied many times since. I won't get into all the examples, but it's a lot.
Sadly, The Kube turned his back on film noir after THE KILLING but at least he went out with a bang. Highly recommended.
