I think they kind of wrote themselves into a corner with the movies since they had no idea that comedy central would pick them up which is why they enter the wormhole at the end of the last movie as a very real ending. Anyone else notice they treat the end of every season as if it might be their last? Seems like comedy central might only be giving them one season at a time.
As an avid fan and owner of the first four seasons on DVD I can say although I do enjoy Futurama to this day I don't find it AS good. As I once did. I don't think this has anything to do with it being on comedy central as much as it does the movies almost forcing certain aspects to the point that it seems to be just TOO much
