Tarantino's classic brand of humor is on full display in his latest flick, which calls back his earlier works in the sense that it's not really about anything – and I mean that in the best way possible. It's not that the movie lacks substance; it's that there is no one, clearly defined narrative goal. The film is ultimately a character study of an actor and his stunt double during a particular time in Hollywood's history, and that's all it needs to be. Pitt and DiCaprio shine as the two leads, and the fantastic supporting cast takes the film even higher. The biggest qualm I have with the movie is that the revisionist history angle is entirely unnecessary. Nothing against Margot Robbie's performance, but her character simply added nothing to the story aside from providing a face for Sharon Tate, who wasn't even relevant until the very end. Cutting those sequences out would have also made the movie's runtime much more bearable. That being said, Once Upon a Time in Hollywood is still a solid addition to Tarantino's filmography.
