DATD agree with Morbo the intergalactic conqueror.

What I like the most about Futurama is the continuity, the pace and the connection between the episodes: Fry and Leela's relationship actually evolves. Leela looks for her parents and when she finds them, several well-spaced episodes turn arround that fact.
As much as I like Aqua Teen Hunger Force, Family Guy and Simpsons (although I haven't seen them for ages), none of those series have that. Family Guy have someting similar but only to a certain extent: when Mr. Weed dies, Peter becomes a fisherman. However, with the exception of a few episodes, I feel FG isn't going nowhere. Don't get me wrong, I love Brian and Stewie duo, but it doesn't really provide anything but laughs.
ATHF has a lot of interesting cultural references and original and unexpected moments but it doesn't have connected episodes: In one episode Frylock moves away, in the next one he lives yet again in the same house and similar things happen all the time.
