It's 20 minutes of cheap entertainment and it's still better than a bad sitcom that is not about geeks.
Maybe it helps that I can't really identify with the characters because everything is so American (and I'm not)?
(it's hard to explain, I never exactly realized which parts of US series--comedy or not--were "show" and which parts are just how US culture is, before I visited the USA. Maybe imagine all the tiny things that are slightly "different" when you watch a European series? Related, there's probably a lot of scenes in European series that make me cringe because they're a little bit "closer" than for a US viewer who maybe assumes it's just part of the show's quirkiness. Dating culture is one of many examples)
