1. The Neon Demon
Probably one of the most divisive films of the festival with strong opinions by all, and all with valid reasons, but I loved the way it was filmed, with some beautiful camera work and editing. The soundtrack by Cliff Martinez is incredible and I am still listening to it pretty much on a daily basis. The cast are great - especially Elle Fanning and Jena Malone - and direction by Nicolas Winding Refn is slick and effective.
My only criticism is that it could have ended a little sooner than when it did. People who've seen the film will probably be able to guess as to which scene should have been the final scene, as it is a very strong scene.
