Mayhem’s review published on Letterboxd:
Tarantino is back, and he does not disappoint, Once Upon a Time in Hollywood might deviate from his earlier work, but is by no means not a Tarantino movie. The more you know about the Mansion murders, the better it is, cause he plays with your expectations. There's a lot of inside jokes and references you'll miss if you are not familiar with the time and setting. But regardless, everyone can find something to enjoy out of this one. Just seeing Brad Pitt and Leonardo Dicaprio on screen together is enough to keep the majority glued to the screen. And they are both stellar in this picture.
