A mysterious illness turn children into killers during a Christmas vacation.

It's exactly what you expect from that description and it doesn't disappoint. The children are effectively creepy, some really nice bloody gory scenes and it doesn't shy away from violence anyone can die including the kids. What's funny is the adults were just as annoying as the children, everyone was screaming and whining. Made me realize how bad I don't want kids!

You can tell most of the film wasn't filmed on location, the snow looks really fake and it doesn't look cold at all which you could argue it's closer to spring but Christmas is usually pretty cold. That being said blood on snow is always a winner.

The ending was great it even had potential for a sequel. Overall a cool little Christmas horror flick.
