It seems Quentin has run out of steam.

Rating: 7/10 (11 May 2020)

Now it's not exactly as bad as some people claim it to be but it's not great either, definitely not a 1 star film and most definitely not a 10 out of 10. If I were to rate it on a scale of 10, I'd give it a 7.
Great cinematography, props and music that successfully captures the late 70s. Great performance from Brad Pitt who most certainly steals the show, as for Leonardo DiCaprio, it's nothing he's not done before, it's pretty much the same as always, he seems to play the same character whichever role he takes on, by this I mean he's performance here is no different than his performance in films such as The Departed, Inception, Shutter Island etc, and Margot Robbie is just about serviceable, hardly her fault, she just doesn't get much screen time and frankly doesn't have much to play with in terms of material, basically any half decent actress could've played the part.
The biggest problem and the one that ultimately drags this film down is the writing or rather the lack of it. Scenes are unnecessarily long, dialogue is average at best.
I've got absolutely nothing against lengthy scenes so as long as they're interesting to watch or when building atmosphere and tension or even character development but regrettably the film offers very little in relation to this and thus adds to the total running time of almost 3 hours which as a result hurts the overall experience.
What could be shown in 2 minutes drags on for 5 minutes and you can't help but disengage from the scene especially when the dialogue between the characters aren't very well written or that interesting to be blunt.
It's a real shame because when it's good it's really good but the good is too few and too far in between, I personally think it was a missed opportunity on behalf of QT to tell a fascinating story about a fascinating time in Hollywood, but unfortunately it lacks the energy and clever writing and sadly falls flat in the end.
