My nephew and I watched it the other night. Myself, I'm still uncertain, though I think its because I was, in fact, expecting more over the top stuff like Family Guy or American Dad without really realizing it

My nephew compared it to a middle of the road TNG episode... like something from season 3 where it just kinda vanishes into the background noise because its neither good nor bad, just is. Which then prompted a brainwave from myself:
"Its kinda like they handed a mediocre TNG script to a bunch of MST'ers, who then have to not only deliver the performance, but throw in their mst's as well."
