Given how Family Guy sucks so much now, I don't know why anyone would want Futurama to come back. The direct to DVD releases were lukewarm at the very best and post-Family Guy cancellation style obnoxiousness at the worst. If fanservice and half assed writing is in the cards for Futurama, like it was on the direct to DVD releases, it is best they not even bother.
I do believe Futurama got a good shot. Successful TV shows have been made without ideal time slots in the past. They succeeded because the writing was good. Futurama I'd consider to be a good show but it was never really funny and relied too much of continuity and canon. Did they expect anyone outside of the die hard set to really give a fuck about Fry's brain waves being so inferior that he is the savior of the universe not in one episode by several? No. I think by the third season, they knew it was doomed so it just became a show for the fans. Might be why I think by Season 4, the show was wrapped up in its own BS to ever really recover, hence the cancellation and the mediocre direct to DVD releases.
