If you're looking for some horror films this October . . .
This list by Benito Cereno is super solid. He focuses on what's available on Amazon streaming, so if you see a thing you like it'll be easy to make that happen.
I have a lot of love for horror films. More than any other genre it's a thing I can watch even if they're awful, just for the analysis aspect.
So here are some off Benito's list that I want to super recommend:
Pontypool -- An exiled shockjock radio talker guy gets trapped in his studio while a linguistic virus wrecks havoc.
Black Death -- Sean Bean leads a team of grizzled witchhunters in the 16th century.
The Devil's Rock -- Irish commandoes in World War II happen upon an island fortress where a notorious Nazi scientist has a demon captive.
Troll Hunter -- A found footage film about a Norwegian man who hunts massive, giant trolls for the government.
The Cabin in the Woods -- Joss Whedon's homage to classic slasher horror doubling as an examination of his own eight yar career as a horror writer.
Evil Dead 2 -- C'mon, son.
The Caller -- A woman, fleeing her abusive ex, gets calls from 30 years ago. An inventive, problematic, tense film.
(Not on Watch Instantly but also worth checking out: The Butterfly Effect 3, Lake Mungo, Behind the Mask: The Rise of Leslie Vernon, and The Decsent.)
