SERIES PREMIERE: The praiseworthy elements of this new NBC sitcom – that its characters and their relationships actually change a bit, if only temporarily, over time – are, unfortunately, mitigated by the fact that I can’t imagine anyone but a stubbornly dedicated TV critic to stick around to watch that many episodes. Even with Bill Lawrence attached as a co-executive producer, Undateable feels eerily, and wearily, familiar, like another of those endlessly subpar sitcoms NBC used to stick on Thursday nights as forgettable mortar between its more successful shows. Some things haven’t changed. Chris D’Elia stars, and is asked to do so much physical comedy, it’s as though his character can’t speak without playing Charades. This is a warning, not a recommendation.
