The number of 10 star reviews is simply not realisitc

Rating: 7/10 (12 August 2019)

I am a long-time fan of Tarantino. I watched both Reservoir Dogs and Pulp Fiction in theaters on opening day in two different cities. I have seen all of his movies in the theater within a week of their release, and I absolutely place three of his films in my all-time top 20 list.
Let me summarize this one as quickly as I can with no spoilers. Tarantino is trying to do two things here - write a love letter to Hollywood of the 1960s and predicated that on a post-facto would-be revenge story about the horrific Manson family murders of Sharon Tate and her unborn baby in 1969. The film making is top notch as usual (my literal one complaint is that DiCaprio did NOT look like he belonged in the digitally manipulated clips - the sweat/oil on his skin did not match the other original actors) and the editing and storyline are very well managed. The reconstruction (digital?) of 1969 LA and Hollywood is phenomenal. It's on par with the job on Roma, which was set in 1970s Mexico City and rightfully won a Cinematography Oscar.
There is plenty to see and talk about in this film. The acting is great, and the fictionalized narratives are realistically believable. It's a fine film.
But this is NOT a 9 or 10 out of 10 by ANY objective scale when taken against the history of film-making. IMDB has lost control of the ability to regulate real and fake reviews. Literally every big-time wide release movie now is flooded by either 9/10 star reviews or 1/2 star reviews. It's ridiculous and the site's credibility suffers as a result.
"Once Upon a Time in Hollywood" is a fun 2hours and 45minutes and a very well made film. It is not an achievement in cinema nor is it one of Tarantino's top 4 films.
