"Seduced: Inside the NXIVM Cult" is definitely worth a watch to anyone interested in cults. I've only seen the first episode yet, but IMO it's very well done (unlike the other recent docu series about the same cult), probably making it to the list of my favorite cult documentaries (along with Wild Wild West, Holy Hell and David Wants To Fly).

You can find the series on Amazon Prime (though not in every country it seems), Hulu, Starz.tv, or on your favorite torrent site if you're a naughty person.

The other thread on NXIVM is under "Large Group Awareness Training, Human Potential" at [forum.culteducation.com] Latest news is that Keith Raniere has just been sentenced to 120 years in prison.
