'Ben and Kate': Will sibling comedy with a heart work for FOX?

The new clip reel for FOX's fall comedy "Ben and Kate" scans like a trailer for the next Judd Apatow-enabled rom-com to hit the big screen. The action centers on Ben (Nat Faxon -- who coincidentally co-wrote the Academy Award-winning "The Descendants") and Kate (Dakota Johnson) -- a brother and sister who "raised each other, but only one grew up."

Kate is a single mom trying to fight her way back into dating. Ben is a mess who blows back into town to stop his ex-girlfriend from marrying some other dude. Along the way, they help each other grow a little bit more. Awwwww! Did we mention that Ben and Kate's fictional last name is -- we kid you not -- Fox?

But since the trailer -- and the pilot we assume -- functions as a self-contained story will the show have legs?

That remains to be seen... on Tuesdays this fall.
