Interesting movie with a fantastic cast, but with some serious issues

Rating: 7/10 (25 August 2019)

First, the best thing was the performance of the the actors Leo and Brad. It was a great comeback for both of them.
The violence and quotes were there as we expect from The director.
On the other hand, there were serious problems:
1- The story telling is very bad, you fell that you watch different scenes that are not connected. The only important story is at the end of the movie. There are no scenes about the Manson family. How they started, what they believe on, and why they tried to kill Sharon. It seemed that every thing was a about luck. That why lots of people including me did not understand the end of the movie. This was the worst thing about the movie.
2- In order to understand the movie you should know about the history of hollywood like the story of sharon tet before watching the movie. This is bad because the normal audience do not know about these stories. At least they should have gave as a warn to read about some hollywood history before we watch the movie. In addition, the name of the movie starts with ( once upon a time...) so, I expect the movie to tell me a story with the details, even if my background info is zero.
Ultimately, it was a good movie. But, it was not what we were expecting for months.
