Documentaries for the snoop in all of us.

It's not new, but the documentary pieces by Louis Theroux are great. I think he banks on an innocent look and a British accent to gain access into some very interesting (and usually closed or secretive) groups...suburban swingers, black supremacists. I'm equally impressed with his ability to ask questions directly and elicit answers that show an honest and human snapshot of these people's lives. Aki thinks they're open because subjects might not realize that folks stateside will be able to watch the videos (thank you Internet)...any other opinions? I suspect that these guys see Theroux as a vehicle to explain (justify?) themselves to the outside world that has a lot of preconceived notions about what they're all about. And true, many of the things they expose about themselves are surprising and thought-provoking, but there's also plenty of reconfirmation of why these people are acting on the fringes.
