There is very little that can be done in a new way with a Manson Family movie at this point. There has been made at least a dozen movies about that case since 1971, one of which came out while the trial was still going on.
The formula is always the same, and anyone who at least read through the Wikipedia page about the Tate/La Bianca case would know exactly what's about to happen: first Charlie is loving and philosophical, then he becomes gradually more crazy, building up to the point of Helter Skelter and, ultimately, the climax.
So it's at least refreshing to see a new sort of Manson, sort of timid and meek, just a misguided ex-con who created a situation that got out of control. It's a little provocative, probably appealing to the pro-Manson crowd, but nevertheless, it is something new.
Problem is, this performance by Ryan Kiser comes off as bleak and dispassionate, and the change in Manson's behavior does not make sense, the character doesn't change gradually - in fact, he almost doesn't change at all, he sleepwalks through the movie up till the end, and there is zero of real Manson's energy put into this performance. I never seen Charles Manson outside his prison interviews and rare footage available on the Internet, but I am sure that he was never this boring in real life. People have always described him as wild and energetic, and Ryan's Manson is anything but these.
In short, if you are interested in Manson Family, check out this movie, but don't expect anything radically new, the story has been told a dozen times, and there's little that can be added to it but speculations and interpretations.
