This is one of those odd situations where you can appreciate the artist but hate the art. At least I did. Gaspar Noé (Love) puts a lot of technical joy into Climax, with interesting camera work, edits, and choreography. He even managed to attack the structure of film in service to his goals. I can’t say I could tell you what those goals were, but the opening of the movie and the first 20 minutes are designed to make you pay attention and to put your expectations off-balance.
But none of the characters he provides us are particularly likable. Even Sofia Boutella (Hotel Artemis) is more repulsive than magnetic. Without a connection to the characters what happens to them is empty, however real they are being portrayed.
Ultimately, I fast-forwarded a large part of the second half of the movie in hopes of finding a purpose or at least a moment of interest. I never did. And the final reveal just didn’t matter to me. There is some commentary on the nature of people in the story, but nothing you haven’t seen before done better. Noé doesn’t even manage to portray the bending of reality for the characters in any kind of new or unique way (like The Man Who Killed Don Quixote managed). So, my recommendation? Skip this and never wonder what you missed. You’ll have missed nothing. But check out Noé’s other work at some point. He is talented and willing to buck convention and expectation to achieve his purpose. When you play in that arena, you’re allowed a failure or two in pursuit of your art…even if that means you more often fail than succeed.
