I got the idea from somebody on Reddit, I think, to watch a horror movie every night of October. I've been trying to keep up, but with work and everything it's a little hard to find the motivation for one every night, but I'm trying!

So far I've done: Halloween (1978), Alien, Aliens, The Amityville Horror (2005), Hereditary, The Lords of Salem, Deathgasm, The Lost Boys, Poltergeist, Black Swan, and House of 1000 Corpses

I saw this idea on Youtube myself, from Jaiden Animations if I remember correctly. It looks like you haven't done Blair Witch Project yet....

I'd also suggest The Haunted Mansion (either original or remake; I'm more familiar with the remake).

blair witch is always great! I may have to add that one to the list
