Well, since NBC always juggles shows in and out of that slot, I've been hard-pressed to treat any of them as regulars. But yeah, all those shows are pretty terrible. THE OFFICE still looks amazing in comparison.
Um, have you watched Outsourced? Or whatever they throw on in the 8:30 time slot?
But my point is that NBC is still offering some terrific stuff on Thursday nights. I mean, last week's PARKS AND REC, with the controversy over the painting, was just wonderful. And COMMUNITY has had its ups and downs, but it's knocking it out of the park at the moment, both with its send-up of the "clip show" episode and now its "too epic to believe" two-parter finale. (30 ROCK is good, too, but it's just sorta "there" these days.)
