Offspring-2009

Survivors of a feral flesh-eating clan are chowing their way through the locals. Amy Halbard and Claire Carey strive to survive their abduction by the cannibals and save their children. A subplot involving Claire's despicable husband, Steven, gives an opportunity to cleverly compare predatory civilized folk to the appetite-driven primitives.
Based on the fantastic book by Jack Ketchum (read it twice).It's kind of a lord of the flies/Hills have eyes/ Wrong turn/Texas chainsaw massacre/Blue Lagoon type of movie. (through that last one in for shits and giggles)
