I, for one, never got into the "reality" show fad, largely because there's hardly anything real about it. Most basic human interaction, even in such wacky and far-out (haha) situations, borders on the banal, which wouldn't translate well onto the small screen. So how is this fixed? Injection of artificial drama
"Okay, you two pretend to hate each other, and you two pretend to have an affair, and you two act like you're going to stab this guy in the back, got it?"
I think there are some parts that are just as scripted as your run-of-the-mill sitcom
Reality show actress: "Fuck you you fucking piece of fucking.... umm.... line?"
Director: "Shit."
RSA: "Yeah, you fucking piece of fucking shit!"
