Because none of the characters are even remotely likeable, which wouldn't be as big of a problem if the show was at least entertaining, but it's about as funny as getting sounded by a white-hot rod of rebar with a medical bill taped to the cold end of it, which is kind of a problem for a show that's advertised as a comedy. Granted, you could have a comedy where every character is either an idiot or a scumbag, and still have it be good, like Blackadder for example. This was not good at all.
