Two precocious adolescent siblings leave their single mother to visit their grandparents whom they've never met, and videodocument the entire encounter, although things are immediately amiss upon their arrival. M. Night Shyamalan's return to twist centered, old fashioned shocks also attempts to incorporate comedy and melodrama, and fails at all three, the scares being routine and obvious, the laughs feebly attempted and geared toward a preteen audience, and the melodrama unearned and coming out of nowhere. The young stars are obnoxious and insufferable.
