Nicole and I watched Climax (2018), a French film about a group of young dancers whose celebration turns nightmarish. The choreography was beautiful and there were some very vivid scenes, but the pacing needed work. Very much a "the horror within all of us" kind of film, but no immediate parallels that I can think of, so I appreciated the novelty. I also liked the horror callbacks in the VHS tapes framing the dancer interviews, which open the film.
