The commentaries on the Futurama DVDs are hilarious! They include a lot of the voice actors, and they go into character a lot! Cool! So, why are the commentaries on the Simpsons DVDs so incredibly LAME? I think it's because the Simpsons people are so obscenely tainted by their wealth. It's clear that the people who made Futurama actually enjoyed what they were doing.
OK, I'll get down off my soap box now.
