Harry Du Bois’s review published on Letterboxd:
As I write these words, a thousand thoughts pass my head — so many things to say about what is essentially a movie that does so little with so much of its potential. I like meandering, slow-going films as much as the next guy, but it’s the first instance in a long time where I went ‘this sluggish pacing does nothing to enhance the film’. I liked Rick Dalton so much (he might be my new favorite Tarantino character) and Leo DiCaprio’s performance, but that’s the only real positive aspect that struck me from the off. Nothing really happened ... and Tarantino’s changing history did nothing to make any sense. Why put Sharon Tate here, if not to double down on her side of the ‘stars slowly losing their face’ plotline that was so effectively shown by the scene outside the theater? The Mansons has no actual relevance to the plot — Charles Manson appears for one scene! — and their involvement makes the whole film this unapproachable, incomprehensible picture that one can only barely enjoy if they already know the Sharon Tate murder.
This may be the only Quentin Tarantino film where I felt next to nothing. No joy, no depth... only a smidgeon of satisfaction of seeing Rick Dalton’s scenes. He’s a charmball.
Final verdict: basically The Man Who Killed Don Quixote, but without a decent enough plot and character that saves the film from being a hodgepodge devoid of purpose or meaning.
