The 2 people that left poor reviews on here obviously don't understand a lick of psychology or anything about cult mentality. They state that the only person to blame is the person committing the crimes or that a person's past/upbringing does not justify rape & murder. And yes, they are correct. A person is responsible for their own actions and rape/murder is never justified. But they have totally missed the point. The point is to show you how weak minded people are easily manipulated into doing things they normally wouldn't. This is why the Manson girls did what they did, this is why Jonestown happened.
Anyway, this episode played out well. The acting was above average for this show (if you've seen a handful of them then you know that a lot of the additional characters are not played by the best actors). The script was also well written. Fast pacing and the lack of subplots kept the story moving. And it showed well what I mentioned in the first paragraph....weak minds are easily manipulated...and yes, it does make sure that those responsible are shown to be held responsible.
