“Family Switch” claims it’s an adaptation of “Bedtime for Mommy,” a 2010 children's book by Amy Krouse Rosenthal. In this story, a little girl playfully swaps roles with her mother for their bedtime ritual, putting the kid in charge of bath and book reading before moving on to her father. It’s a cute tale, but it isn’t the story used for “Family Switch,” which pulls inspiration from Mary Rodgers’s 1972 book, “Freaky Friday,” which has been adapted for screens big and small multiple times, and ripped off even more. Perhaps there’s a legal issue standing in the way of true credit, but role-swapping turns into body-switching in the new film, with director McG offering a hyperactive understanding of comedic possibilities involving parents and kids in awkward situations, creating an unexpectedly aggressive viewing experience that immediately suffocates all emotion it offers, while its overall sense of humor is dispiriting. The production would’ve been better off actually turning “Bedtime for Mommy” into a movie. Read the rest at Blu-ray.com
