A pretentious, convoluted mess. After an intense opening scene, this abomination continued to suck all life out of me, making me completely emotionless and indifferent about the story and every single character. On top of that, the audio quality is horrible, but that's Christopher Nolan's specialty (Dunkirk being the notable exception).

Tenet was the first movie I watched in true 4K on my home theater setup, but I remember few movies that I enjoyed less.
