“Frozen’’ has its work cut out for it, since the main characters are so annoying you initially pray for an avalanche to just get it over with. Dan (Kevin Zegers) is a smarmy prep who pimps out his girlfriend to flirt with a ski-lift operator for free passes; said girlfriend, Parker (Emma Bell), is a whiner who has been falling down the bunny slope all day. Dan’s best friend, Lynch (Shawn Ashmore), is a slacker ski purist who sneers at the other two’s snowboards. Check, please?
Yet writer-director Green (a Holliston native now living in LA) generally plays fair by the premise, with one or two big, honking exceptions; see below. “Frozen’’ is an effective, no-frills gruel-a-thon if that’s your cup of Swiss Miss, and it explores such burning questions as: What happens if you’re dumb enough to leave your bare hand on a metal safety bar overnight? What does frostbite look like if you scratch it? Is it possible to shimmy along a lift cable without severing your fingers? And - a crucial one - when did wolves come back to New England?
“Frozen’’ was shot in Utah but it’s definitely set in our neck of the woods - Wachusett gets a call-out - and it shares with the much more inept “The Canyon’’ the ecological novelty of wolves where there ain’t none. I suppose if you can suspend your disbelief the way the heroes are suspended over the abyss, strands of cable ping-pinging apart one by one, you can accept the suspense of their possibly becoming doggie dinner. Harder to buy is the fact that none of the three are packing a cellphone. When screenplay necessity trumps logical realism, you have a problem.
So, yes, “Frozen’’ is silly stuff, but I admire Green for seeing the situation through and ultimately coming down to the nerve-racking spectacle of two stressed people going into their third day aloft in sub-zero temperatures. No green screen, no special effects; just a little fake blood and a few stunt wolves that look like their trainer tops them up once a day with New York strip. “Frozen’’ is a functional nightmare for ’boarders and those who love them - the “Worst-Case Scenario Survival Guide’’ of horror-suspense.
