This is two distinct films clumsily stitched together.

First two hours is about a actor on the way down (Leonardo DiCaprio) and his stuntman buddy/gopher (Brad Pitt). Nothing much happens. DiCaprio is particularly poor. The best performance in this section is from an 8-year-old girl which gives an idea of what calibre of production you are watching.

The last half hour is an unpleasant reimagining of the Sharon Tate murder in which Tarantino includes his two fictional heroes. It's set six months later and makes extensive use of narration to explain what is happening - always a sign of poor writing.

You get the feeling that the "short" at the end is the film Tarantino really wanted to make, but he had to add two hours of Hollywood nostalgia at the start to make it seem anything other than exploitation.

The cars, clothing and sets are all lovingly created at great expense. But outside of a handful of scenes (Margot Robbie at the movies, Pitt at the old ranch), it's nothing more than a poor movie with a nasty ending.
