We're now into the "Why hasn't that premiered yet?" portion of the Fall as Fox's new animatedpremieres tonight at 8:30pm between The and .
How will it rate?
Handicapping help: Although it's been four weeks since Fox has aired a "standard" Sunday night schedule, its animated show ratings this fall have ranged from a low of a 2.6 adults 18-49for to a high of 4.8 for . Also, I'm pretty sure that New England @ Pittsburgh on CBS is the late national NFL game today, so Fox should not see a big primetime NFL overrun tonight (although CBS is likely to). Update: As the always informative Julia notes, tonight is the Treehouse of Horror episode which typically sees a nice ratings bump.
Feel free to expand on your guesses in the comments.
