It is difficult to describe the point of Climax.
A dance team has finally nailed its act. Before taking the show on the road, it’s time to party! The crew relaxes, dances, gossips. It’s a good time—until somebody spikes the punch. Whatever was used, it does not mix well with the crowd.
Watching these pros dance is a good time. Music and camerawork help you experience their flow. But at several points, the director interrupts: with advertisements, credits, or philosophical messages; it’s unclear. Put that choppiness together with the horrific descent of the characters into lunacy, and the movie can feel unapproachable. Maybe that’s the point?
