Yeah I am definitely buying the DVD, but I don't have Comedy Central where I am, so I'd have to wait a long ass time to actually get to watch it.
SPOILERS!
I feel like it was all over the place because they were trying to reintroduce everyone to the show. They weren't trying to make the best episode with this first one, they were trying to cram in as many characters as possible so people would remember everything they loved about the show. Otherwise there is no reason for Zap to be there, no reason for the entire space battle scene, and a lot of other stuff that wast just clearly like "hey, remember how you love our show?"
Also, the best line by far was "I'm the professor! I can wire anything to anything"
