There are many great shows out there that get cancelled way too early. This thread is for those shows.
The show that immediately comes to mind for me is Freaks And Geeks. Freaks And Geeks is one of the greatest TV shows of all time. OF ALL TIME! And yet, the fucking morons who run NBC decided to cancel it before the first season even ended. The episodes eventually played on Fox Family Channel( now ABC Family), but of course, they didn't have the common fucking sense to pick it up for another season. So now, we're left to ponder how the show would have played out if it had gotten a second season.
Undeclared is in the same boat. Fantastic show with a lot of heart, but never made it past the first season.
Futurama should have never been cancelled the first time by Fox. Same with Family Guy, although Family Guy has definitely run its course since being brought back.
I know Married... With Children ran for a really long time, but I wish it would have gotten a proper series finale instead of the two part episode it got. I mean, the two parter was funny, but it didn't feel like a proper ending.
There are some other shows I may go over, but I want to wait until this thread gets more replies. As soon as people join, damn it!
