That show is mostly about cheesy drama and cringe. Don't get me wrong, I watched all of it, but I never would have watched it if my roommates didn't.
But there are really funny parts, but those honestly end up being inside jokes, meaning you have to get to know the characters.
I was the same way with It's Always Sunny in Philadelphia. I had the TV on in the background and it was on FX, just programming, and the episode where Dee and Dennis get addicted to crack to get on welfare was on.
Until then, I hated that show and couldn't get the hype.
(on a side note, that show went to shit by season 7... so it goes)
But I digress: once you learn the characters (and starting at season 1 is rough because the characters aren't really developed yet) the Office becomes much more entertaining.
