I'd love to find and watch some gems I've missed. Can others suggest movie(s) they think others have likely not seen, but really should, starting from ~2010 up until today?
Obviously movies like Get Out are not in the "deep cut" category.
Yes, good choice! I happened to see it, but yes, that's in the ballpark of what I'm looking for here. Something that was not a "major" horror movie, but actually far better than high-profile ones that get more attention. "Better" being subjective, of course, but I want others' opinions on what they think is a good movie that may have been overlooked.
Not sure how many of these count as deep cuts, but here are a few from the last decade (or so) that I enjoyed:
Pontypool-Actually came out in 2008, but it's still worth watching, especially if you are looking for a zombie film that does something different. A washed-up radio DJ listens from his booth as his town breaks down around him following an outbreak of a mysterious infection. It definitely leans more toward psychological horror rather than traditional zombie horror, so I could see someone complaining that it's slow and doesn't really show anything until near the end.
Butterfly Kisses- A found footage film about a film student investigating a found footage film. Maybe a bit too meta for some, but I enjoy a found-footage movie that doesn't take itself too seriously. It seeds just enough doubt about whether the footage is "real" that it leaves you guessing how it's going to end.
Triangle-2009 film about a group of friends who come across a seemingly abandoned ocean liner while out on the water and decide to explore it. Maybe not that deep a cut, but it's worth checking out if you've never seen it.
Coherence- Not actually sure if this counts as horror. I see it classed as a sci-fi thriller a lot, but I found it while searching for something similar to Triangle. A group of friends gets together for a dinner party only to notice strange things happening after watching a comet passing overhead. It's hard to say anymore without spoiling it. Another one that could be seen as slow and without a lot of "real" scares. Still might be worth checking out if you want something that is slow-burn and more psychological.
I don't know how deep these might be, but I'd suggest Vivarium, Landmine Goes Click, and I Saw the Devil. Those are from 3 very different horror subgenres so hopefully at least one is appealing if you haven't seen them already.
I have seen all these, but I don't remember much from Dark and the Wicked. I think I might have had my head in a laptop while it was on; I may have to rewatch that. Thanks for the recommendation!
