Alasdair Wilkins of The A.V. Club gave this episode an A - stating: "The episode features Kim Kardashian, a move that should feel like shameless stunt - casting, except she's on hand to play a furry pink alien; this is in keeping with American Dad's admirable habit of reeling in impressive guest voices and casting them in unrecognizable roles . The episode features Roger and Stan at their most casually sociopathic, yet both find just enough hidden emotional depth for the episode to not feel completely mean - spirited ." </P>
