Don't be surprised if the movie's most wince-inducing moments come not from the "disturbing images" (as the MPAA describes the sight of a leg bone sticking six inches out of one character's ski pants) but rather of the bad acting and worse dialogue.

Frozen delivers enough thrills and gory chills to satisfy the horror film crowd, but is not written, directed or acted well enough to be a first-rate thriller.

It’s the audience which may be left feeing stranded by the film’s wobbly characterizations and drawn-out drama.

Green also can't maintain the suspension of disbelief necessary as we watch three charmlessly written characters bicker and attempt inane ideas. It's one thing to be scared with them, and quite another to feel trapped with them.

Better to defrost "Alive" or "The Edge" from the video icebox.
