From the interviews and documentaries I've seen about Manson,, I'd say Smith nailed it here. He had me believing that he was Manson (hopefully he didn't go TOO method). Murray (loved her in GoT) plays the brainwashed groupie perfectly. Wever (loved her in TWD) does a great job as the counselor trying to bring the women back to reality. Overall, this is worth a watch. I'd give it a 6.3 rating.
