Aw, man! They cancelled GCB? That was such a fun show.
If we're talking about shows we've never got over being cancelled, I have to admit to still harboring bitter feelings over the loss of Jeremy Piven's "Cupid". It's been about 15 years now, but I loved that show. <sigh> I still have all the episodes on tape. Sadly, I no longer have a VCR, but I can't give up that tape.
I'm also still bent that "Terriers" was cancelled. That's been just over a year, but at least I have that one downloaded onto a hard drive.
