For those who are clueless about skiing
ALL, and I do mean ALL ski resorts in the world have a very simple policy that would prevent this very sort of thing from happening. One the resort closes, the report rescue squad rides the lift to the top of the mountain, checks every room and locks up, and then makes the last ride down. Lift operators do not control the final run of the day. This holds true worldwide. I've skied in the East, the Rockies, the Cascades, the Sierra Nevada, and Europe and this is an international regulation adhered to by all ski resorts. Many a time I found myself the last skier up the lift and in the chair in back of me was the ski patrol with the ski patrol operating the lift. The ski patrol never let me get behind them going down the mountain. The entire premise of this film is silly.
And where do the wolves come from? There is no report in the lower 48 that could be threatened by wolves. I'm trying to think of any resorts in Canada. There are no wolves in Europe or South America. The only place with ski reports and the potential for wolves in Alaska.
Wolves rarely attack humans even when they are in a pack. They avoid humans. A pack of wild dogs would be more likely to attack a groups of humans or a mountain lion. The skiers are armed. Anyone who's ever spent any time skiing understands the danger of getting impaled by a ski pole tip. Three skiers = 6 3 ft long de facto spears. That's plenty to defend against against a wolf. There is also the sky. I once got knocked unconscious in a collision when I was hit in the head with a ski.
This film is so improbable. I can't watch films that fabricate dangerous situations out of whole cloth. There's greater probability that the chair would fall off the cable then getting trapped mid slope on a lift.
