Get Out
I know it's intentional, but I felt like it was a little slow to start. That's basically my only gripe here. This movie is excellent both in terms of objective quality and social commentary. I felt like there was a little bit missing after finishing the movie but soon after I watched "Horror Noire" - a documentary about the history of the black horror genre and the doc as a whole along with the specific commentary on "Get Out" allowed it to fully unlock for me. On the list of movies I wish I could go back and see again totally blind, this ranks very high.
