Us Rating: ** 1/2

Star power -- and yet another overblown new-house reveal -- trumps substance in what should have been a truly heartwarming episode. Sheryl Crow and Miranda Lambert join the team in Tulsa, Oklahoma, to assist the Starkweathers, whose son Ethan has a rare disease marked by intense hunger pains. The inspiring 9-year-old is a real charmer, but he’s also sadly lacking in screen time. (ABC, 8 P.M.)
