This is probably the best horror film I've seen this year, by simple virtue of being the most plausible, but it also qualifies as best acted and best written. A touring punk band accidentally takes a gig at a neo-nazi compound, and things progress steadily worse from there. There's exponential escalation in tension and suspense, even before the brutality begins. Once that starts, it's pretty horrible, as no one has ever scolded neo-nazis for being cuddly, but the villains are well written and intelligent. The main characters are extremely likable with great chemistry, especially between the late Anton Yelchin, who turns in a fantastic performance with his previous co-star Imogen Poots. Because you genuinely grow to like the characters, its more impactful when one of them suffers. It is a terrifying scenario, good morality play, and one of the more horrifying films to come out this year.
