This movie is pretty, has good dialogue, takes its time, sets a scene, characters have an arc and is overall entertaining, even if some might say not a lot happens.

However there is one critical oversight. If you are not familiar with Sharon Tate and the Manson family you will not "get" this movie fully. A history I didn't realize I had to be familiar with before I saw this movie.

You won't get why Leo is in a movie in the movies reality (which was originally not Leo) while Margot Robbie is in a cinema "pretending" to be someone in a movie she wants to see, she's not digitally placed in it, so she must be pretending to be the actress in said movie. Once the movie is finished you'll think that Margot's entire character was better left on the cutting floor to speed the pace up, missing the point completely that she was the main plot thread.

The tension in one of Brad Pitts scenes comes across as something clearly isn't right, yet as a viewer you will not fully grasp why exactly this scene is tense.

Charles Manson makes an appearance, as a viewer you'll think "Ok, a cameo by someone famous, I don't know who this is, fair enough". While it was Manson meeting Sharon Tate, a big deal and to people in the know a creepy wow moment.

There are other examples but I've made my point. This movie appears to be about Leo and Brad's character finding their groove back in the Hollywood movie industry, but it really isn't, the main plot in the movie revolves around Sharon Tate seen through snippets in the other characters world.

This movie could have been an 8/10. I'm now familiar with the history behind the movie. I wasn't however when I first saw the movie and I can't experience it again as a first viewing now that I know. That's disappointing and for this critical oversight im giving this movie 6/10.
