I've never heard of Glee, but I've just read a summary of it and it sounds awful. I have, however, heard of Kings of Leon, and I know they're awful.
It's one of those rare shows where the execution far, far, far exceeds the horrible premise. It's a fluke show. The only people I've met who disliked it and who've actually
watched it (as opposed to simply saying they have) are those who went in hating the premise and didn't give it a chance despite watching it. Not surprisingly, most of them tend to just overcompensate in everything they do anyway, too.
Their loss. It's a fun show, especially the first half of the season.
