Barbarian
This film balances mystery and horror so well I'm shocked. At no point in the film can you tell what's coming and I mean that in the best way possible.
I don't think I've seen a horror film that's shot as creatively and engaging as this one, it creates an uncomfortable sense of fear that you just can't explain.
I've been wanting to watch this film for ages and usually when that happens I hype a film up too much for myself and it ends up disappointing me, but that was absolutely not the case here. Fantastic.
