I love stuff just like that. I can watch that kind of thing all day--a guilty pleasure I guess you can say.
I've been watching reruns of nip/tuck (I don't know why), and a Hulu show called The Bisexual. There's a show called The Vow about that's NXIUM cult, but I know I'm spelling that wrong, and a doc about a guy like Dirty John where all the women he scammed are trying to find him to take revenge. I don't know the name of it...oh yeah it's called Love Fraud.
I recently saw two docs, the one about the portrait of Wally, and the real inventor of the VW.
