SEASON PREMIERE: Last year, this series plodded on without its creator Dan Harmon, whose departure from the show was more the network’s idea than his own. Tonight, after a long fall hiatus, Community is back, and so is Harmon, with an episode that jumps forward in time for a Season 5 shuffling of the deck, or at least the premise. “We can ‘Repilot,’” one character says, employing the title of the episode itself. “Like Scrubs, Season 9!” And they do, though, it seems, no more impressively. But still, there are loyal fans of this series, so here it is.
