Futurama was so much better and I am a bit...irritated that Family Guy was brought back and Futurama wasn't. For that matter, FOX is still on my shit list for canceling Futurama and Firefly.
Also the great show Wonderfalls which was also cancelled by FOX after only one season.
Futurama is coming back... But honestly, I've long preferred Family Guy's anarchy to The Simpsons and something in Futurama just never grabbed me. I just like how FG is guaranteed to go nuts at any moment. The whole thing is absurd and it's great.
I haven't heard of any of those.
