Didn't see a thread, so here it is. Airs this Thursday on NBC. First review....
Other than the systemic travails of NBC, I have no idea how "Community" is still on television. I have even less idea of how Harmon is back in charge of it. But the whys of it are much less important than the wonderful, hilarious, poignant fact itself. "Community" is back, and back to being itself.
As with so many things that happen at Greendale, it's best not to spend too much time thinking about the reasons behind it. Just enjoy that it's happening, and that it's so much damn fun.
