Cheaters is so low-budget it is funny. They show the accuser their "evidence" on a cheapo video camera. There are two hosts, one is really annoying, the other one hasn't quite figured out how to be so damn annoying.
Funniest ones are the ones they do on the gays. Straight people show allegiances at times and tact, with the gays in the follow up interview it is like "well I got over Michael by going out to our old bar and taking three men home with me".
