Xplodera’s review published on Letterboxd:
More than any of Quentin Tarantino’s previous films, I feel like this does a constant balancing-act between a light, superficial ride and something heavier with emotional depth. This tightrope, Once Upon a Time ...in Hollywood walks phenomenally. It’s incredibly nice to surf along with; the sense of the times is infectious and the music is very groovy. Then the music transitions into Margot Robbie embodying the dancing innocence of Sharon Tate and the film reaches something more. The same can be said for Leonardo DiCaprio and Brad Pitt spitting fun banter in entertaining performances, yet Tarantino manages to find a spot in their friendship and the suffocating sense of being pasé that elevates the film to an emotionally potent drama. There are times when it veers a bit too much towards lack of substance, like many of the cameos feeling unnecessary and it’s difficult to balance this many characters in a long film.
Yet it’s probably because of the grand ambitions and epic amount of content that this is such a triumph. It’s a fun, entertaining and great looking film, but with a cast anchored by an astonishing Margot Robbie Tarantino proves that he has more than that and cements this as a truly gripping film reaching beyond simple escapism.
