Be advised: This Is Not A Horror Film I have no idea why they decided to market it that way, or even to name it "Wendigo" when the legend really isn't what the film is about, but merely a story the boy hears and takes to heart.
I did like this movie, surprisingly, being that nothing really happens until the last 10 or 15 mins. But it's got some fine performances all around. The story has some holes in it, but I guess they all do at some level. It's just a good drama about a family that goes upstate (NY) for a snowy weekend getaway and runs into some gun-happy yahoos in a decidedly unpleasant circumstance.
It flows from there, the formula being 'city folk agitate locals', which never ends well, this being no exception. Just go into it knowing it's a simple drama and you won't be disappointed.
