I agree. Any show like this has the potential of being sensationalist, but I think it also teaches a lot of good information. I also recommend "Escaping Evil" on the biography channel. Its a show about people who have lived in a cult or under cult-like situations. Since a lot of what they experience overlaps with what it is like to be in an abusive situations, I think it can be good for rooting out the lie that it is the victim's fault.
