Some that immediately pop into my head:
Krampus. It's mildly scary but the audio and atmosphere is phenomenal.
Trailer Park of Terror. Just sit back, drink a couple of beers, and enjoy this B-rated movie in all it's glory.
Slither. Horror comedy that's great for people who don't like a ton of scary but don't mind blood and gore.
Tucker and Dale versus evil. A comedy with a unique perspective to the horror genre. A must watch!
The earth is really going to suck to live on here pretty fucking soon.
