Any television show that reasonably intelligent people would describe as horrible but many people watch religiously anyway because it is just so bad they can't bring themselves to look away or change the channel or, God forbid, turn the tv off. Most "reality" tv shows would fall under this category.
"I can't wait to get home and watch Survivor, Beauty and the Geek and The Apprentice. Too bad I'll have to Tivo American Idol and Dancing with the Stars. Just can't get enough of that car wreck tv!"
