I'll throw some I haven't seen here yet
Talk to Me is one of the best horror movies I've seen. It's original, well written, and nobody acts like they're in a horror movie or makes blatantly stupid decisions.
If you haven't seen The Others yet, it set the bar for what supernatural horror could be.
The new boogyman movie is a little 'modern', but it's solid and has some really cool scenes.
Tigers are not Afraid was one that came out of nowhere to me, it's a Mexican indie movie about children dealing with cartels, and it's heavy as hell.
For less actually scary and more campy, Satanic Hispanics was a lot more fun than I expected. It's an anthology movie similar to VHS with each piece made by a well known Hispanic director.
And if you want tone upset for the rest of your life, watch Antichrist by Lars Von Trier and Mother! From Darren Aronofsky without reading anything about either of those movies.
