This tepid, straight-to-Netflix chick flick is a case of "tragically misapplied" comedic talents, to bogart a Bartletism. Comedy giants Amy Poehler, Tina Fey, our lady of May Maya Rudolph et al. drink and snipe their way through the Napa Valley, and it is a whole lot of nothing. The Good Sisters story-doctor the hell outta this one. Next week: Big Mouth!
