I actually bought this for a friend, for her birthday. She is very into learning about criminology, especially female criminals, so this seemed like a good fit. We've watched a few of the episodes, and they are informative, if a bit dramatic. She really enjoyed them, and I feel this show is a good fit for those intrigued by the macabre.
It should be noted, however, on the "two seasons" contained within, there were a total of apparently 9 episodes (a minimal 3 in season one, and 6 in season 2). In all honesty, I had been expecting more. It seems it had originally been a miniseries.
