Glee is debatable, but isn't Moder Family just about a family? I think some of you might not quite get what Biggskip is aiming for with this thread. You might not like Modern Family, but as far as I know (I've never sat down and watched it) the premise isn't ridiculous. Same with Jersey Shore, which just falls into the "reality tv" category. What are shows that have premises that make you wonder how they ever got the green light? Like Cop Rock, a serious cop drama that also has musical numbers, or Small Wonder, a sitcom about a guy inventing himself a freakin' robot daughter.
Yeah, I was going to suggest "What a Dummy", but really, the problem with the show wasn't the premise (which was not that far-off from Alf,) but rather that it was just so poor in execution.
