I agree so much with your Halloween musts and that you mentioned Trick R' Treat I love it and think it's kind of underrated. Great movies to watch this season, I also try to see as many movies as I can. I already watched The Exorcist (will probably watch again), The Conjuring, Evil Dead, It Follows (it has become a favorite), The Babadook, Village of the Damned, ANOES: Dream Warriors, A Nightmare Before Christmas (I tend to watch it around both Halloween and Christmas) and yesterday Hocus Pocus.
