Warning: This contain spoilers.
This is supposed to be based on the Manson murders and yet this movie has no gore which I found extremely insulting because those crimes were awful and should not be sanitized which it was not only by the lack of gore but also by not showing a lot of the murders and they did not even show a second of the pregnant woman when she got killed. It did have a few moments that were tense at the start which gave me hope but it went nowhere. In the IMDB page it says that the rating is R which makes the rating system more of a joke than it already was before that movie!
The directing and music are good. The acting, cinematography, sounds, story, sets, makeup and costumes are average. The special effects and editing are bad. The script is very bad.
