Velvet Buzzsaw
I found it extremely entertaining, if not necessarily as deep or surreal as it wants to be. We all agree that true art is when you're poor and selling-out turns you dead inside, but it feels a little rote. The characters come off more like archetypes, which is mitigated by the fact that the cast is very good, and they're all having a lot of fun. Gyllenhaal, Rene Russo, Toni Collette, Malkovich, Daveed Diggs. Gyllenhaal's career is taking a course somewhere between the understated self-parody of Keanu and the overstated self-parody of Cage. I am here for that. Plus, the horror elements manage to be both funny and get some good scares.
So it's pretty good! But for a horror/satire set in the art world, I'd say Deepest Dark is better.
