Ok,I've to admit even though this didn't make me lift a finger,it really scared the holy crap out of my brother when he watched.he still remembers it up to now.basically it's about this babysitter who gets terrorized by a killer.she gets a phone call saying "have you checked the kids lately?"tension starts from there.she calls the cops,and the call gets traced from inside the house.creepy enough,eh?the rest of the story will probably give your kids under 8 nightmares so don't buy it for them if you are not confident.i won't spoil it but it's really intense.go watch it first before you let your kids.
