Writer-director M Night Shyamalan (The Sixth Sense, The Village, Lady in the Water, The Happening) dials back the preposterous plot twists for this simple, low-budget, "found footage" shocker. A pair of tweens (Olivia DeJonge and Ed Oxenbould) are shipped off to the rural farm of the grandparents they've never met. Unfortunately, Nana (Deanna Dunagan) and Pop Pop (Peter McRobbie) seem a little ... weird. This winking, modern riff on "Hansel & Gretel" is a fun, PG-13 horror-comedy that works far better than expected. FULL REVIEW:What’s the twist in M. Night Shyamalan’s new “old people are scary” thriller? ... That it’s a decent film. by Devin D. O’Leary (9/10/2015). 94 minutes PG-13.
