What's not to love about Doug Ellin's big-screen adaptation of his since-retired HBO comedy? How about: no plot; no fresh characterizations; way too many "celebrity" cameos; jokes that are repetitive and shrill; and a pervasive bro-ness that reads both offensive and so-last-decade. Blown up large, the slightly mocking tone the 30-minute TV show offered — mildly sending up the vapid entertainment industry and the dubiously talented meatheads out to conquer it — simply becomes a tone-deaf celebration of the same. (However: If you loved the TV show, you should dig the movie, which is simply an extra-long episode, broadcast years out of date.)
