If Tarantino hadn't directed this it would have a 4/10 rating

Rating: 4/10 (11 May 2020)

This film fails in the fundamental aspect of cinema - to have a plot.
'Once Upon a Time in Hollywood' does not have a plot.
It is simply a succession of events of no particular interest, or relevance, squashed together.
The only thing in the film vaguely resembling a plot - I won't reveal what - happens briefly halfway through for around 20 minutes and then pops-up again for the final 10 minutes. What is the point of the other 2+ hours, I have no idea.
If anyone other than Tarantino had directed this, it would've been panned. Yet, as it's him, it receives this utterly unjustifiable rating.
Perhaps this is actually an art installation by Tarantino; Tarantino proves he can receive copious plaudits by squashing a load of 'stuff' together and calling it a film.
I would say that some have lost the plot by approving of this film. But there is no plot to lose.
No plot, no point.
