Additionally, I'm kind of stoked on the return of Torchwood, about which I hadn't yet heard. Wikipedia says it's a 10 episode run, too. I just hope it's a slightly peppier ending than the ending of third "season". Man, that was depressing.
EDIT: Holly not coming back to The Office, especially for Carrell's last season, would be a HUGE malfeasance for malfeasances sake.
I concur with Big Bad for the most part...I liked the ramped up plotting when they came back in January, as a parallel to how fast technology can evolve, but in the last few they just didn't have enough time to fit it all in.
