Schlock Horror’s review published on Letterboxd:
When Once Upon a Time... in Hollywood was first announced, the word on the street was that this was going to be a story that incorporated the Charles Manson murders and would lean into the horror genre. So as a horror movie fanatic, I was excited to see what Quentin Tarantino would bring to the table. The true-crime is legend and horrific. How would he be able to translate that to the screen without offending the victims?
Well in usual Tarantino fashion, he took a horrific story and spun a sort of fable that alters the history of the true-crime as he did with his Hunting Nazi movie Inglorious Basterds. At a whopping 2 hours and 40 minutes, I was in for the long haul. I really dug this film. This is mainly about that friendship between a fading actor and his stunt double and Brad Pitt and Leonardo DiCaprio are fantastic in the film, as is the entire cast no matter how big or small the role turned out.
From the production design to the cinematography and music. It's a Quentin Tarantino picture, you have one of the greatest filmmakers in his element and he delivers in spades. I also loved the final 10 minutes of the film where shit gets real dark and violent. I would love to see a Quentin Tarantino tackle a serial killer flick that is in the same vein as Zodiac or Se7en. He would do something special. OUATIH may be a little tonally uneven at times and the runtime may hit a few slogs here and there, but this is another great film by Quentin Tarantino.
