Yeah, there were some good moments, but like any show that's been on the air a long time, the evidence that it's been on longer than the creators can keep up with rests in whether or not the show has developed an unnatural obsession with one topic. Every new episode of Spongebob is about the Krusty Krab; every new episode of South Park is about Cartman and reads like an Aristocrats joke that never reaches the punchline; every new episode of Dexter is about fighting the light and darkness while Deb fucks someone in the background; every new episode of The Office is about... I dunno, I stopped watching it years ago, is it even still on?; every new episode of Doctor Who is about the Doctor almost dying FOR REALS and the universe being reset for the next episode so we can see Pond and The Doctor together for many more series to come; and every new episode of my life is about pain, humiliation, stress and diarrhea. Likewise, one too many of Futurama's new episodes feature Fry and Leela's relationship as a main plot line, and it gets old really fast. It's not even a matter of "will they or won't they" anymore; that story arc ended seasons ago. Now it's about trying to bring back the same feelings Jurassic Bark and Luck of the Fryrish wrought, except with their relationship as the vessel for emotional exploitation - a la the episode where Fry is killed by a bee sting - every other new episode.
Futurama is still a well-written show, but the writers' enthusiasm and wit is beginning to spoil. I'd rather the show stay dead than become one of the shows listed above that I now despise. The only other channel that has expressed interest in carrying it is Fox, and - honestly - Comedy Central was the best thing to happen to Futurama. I don't think Fox would continue to give the writers the same freedom of speech they enjoyed at Comedy Central. Ever notice how the show became raunchier and more outspoken?
