Scary movie recs for Halloween!

As Halloween approaches, I have suddenly experienced a resurgence of love for good horror movies. In this post, I will share a few of my favorite non-obvious films (meaning no major Hollywood productions or horror classics, as much as I love them) that are a good fit for the season, with the hopes that people will share theirs in the comments.

I'm not promising that this is the most obscure shit ever (as I'm praising [REC] to the high heavens under the cut and it's pretty well known these days), but I love unearthing scary movies that I might not have heard of before. If I see anything good between now and Halloween, I'll add it to the list.

Please feel free to add your own suggestions in the comments! Older movies, foreign movies, indie movies, anything that isn't incredibly well known is welcomed. I'm planning on watching a lot of scary films through the end of the month, so this post will probably be updated until Halloween night. I'm currently checking out some of the great Hammer vampire classics.
