Would not recommend. Except to Tarantino himself.

Rating: 4/10 (24 August 2019)

I can't in good conscience give this movie more than a 4.
Do you know Charles Manson? No? Then this movie was not made for you. If you do, great! You might actually like it.
*** SPOILERS
At least, 2/3rds in.
I didn't know Charles, but I knew about Sharon Tate. In the end, after watching the whole thing and disliking aspects of it (mostly sound design, the good awful editing choices during most of the movie, and the blank and LONG scenes of people riding in cars), I could piece together that this is another alternate universe like Inglourious Basterds. Still, the way things are presented, the point of many scenes and pacing is just.. wrong.
It's a beautifully shot film, full of care and love for the physical space it was recorded in. Almost no digital manipulation of streets, cars, stores and others. But I feel like it was butchered in editing (jumpy cuts, some weird musical choices, and angles). At a point, you even realize you are watching TV (an old one in a third of the screen) for a couple of minutes during a movie!
And the best performance + lines are given to a child that appears for 5 minutes tops!! Second best is a dog. Still, Brad and DiCrapio do a great job with what they are given.. but it's still long and uninteresting (specially at the beginning), which is weird for Tarantino. Characters that are nothing (specially Sharon if you don't know who she is) and conversations that are dull.
It's hard to recommend to anyone. And while I applaud Tarantino for making something so rare.. I feel like it's a movie made for him only.
