Er, the "spliced up" thing sounds like crap to me, because I just watched "Beast" on Comedy Central, and they showed it as a movie, but with credits for each part. So why the hell would they plan out this convoluted idea, and then spoil it before they sell it? They might as well cut up Back to the Future and pretend it's a TV series. Idiotic. Why didn't they ever show Bender's Big Score?
Critically, I must say the second movie (didn't see the first) was fairly... solipsistic. Why on Earth was the univeral disaster exclusive to only... Earth? They went to Kif's planet twice, but that's it. The tentacle only attacked Earth. Did the rest of the universe disappear? It didn't make any sense. Actually I remember them showing the weird blue aliens from that one episode, but they still only dwelled on Earth getting attacked.
