"A resoundingly old-fashioned and well crafted study of evil infecting an American family, "Frailty" moves from strength to strength on its deceptive narrative course. Though Brent Hanley's script feels like it's based on an account of white Anglo-Saxon serial killers run amok in middle America, it's a genuine invention that has its cinematic roots in the rich soil plowed by such disparate works as Charles Laughton's "Night of the Hunter" and Tobe Hooper's "The Texas Chainsaw Massacre." Pic's dark-night-of-the-soul mood derives from the former, while the latter inspired the notion that the family that kills together stays together. Final effect is of a timeless work that could have been made at any point in the past 20 years." - Robert Koehler, Variety
