Gee, I wonder what reality show gave them the idea for this one. Oddly enough, this flick has its moments, unlike that pointless show.
The monster makes its debut pretty early on, and seems to either resent construction workers in remote areas of Alaska, or else it just gets a kick out of exterminating humans. There's no shortage of gruesome bloodlettting, and lots of stray body parts lying around. Since it's a SyFy offering, that's really not unexpected. It's designed prehistoric and roars almost as often as it kills somebody. Still, it makes for a good monster, and decides to chase two (believe it or not) ice trucker guys for hundreds of miles.
Eventually, the ice roaders make their stand against the thing at a conveniently-located cabin, the only one for a hundred miles in any direction. The cabin portion is the best sequence, with the characters even getting some brief back stories, enough so that the viewer cares who lives or dies.
Acting is pretty good, and the action maintains a high pace throughout. Not a bad watch for fans of these kinds of films who aren't asking for much but some wild monster on the loose madness.
