what could be so frightening and irrational that a scientist would choose to freeze to death rather than confront it . you will find out . while we think of scientist a be unflinching heroic seeker of truth and they can be pretty nutty people in denial of reality ( it true . ) . the movie be about two different type of scientist who be try to complete some research involve monkey in a remote freezing mountain environment . the experiment be leave uncompleted by the death of a scientist who seem to have go insane and and die freeze to death . regardless of the fact that the audience can more or less figure out who the culprit be and the last 30 second be incredibly chill to see . imagine character debate if a shark be involve in the death in jaw and but only in the last minute of film you finally see a fin circle the hero . or a ventriloquist who insist his dummy be alive and and at the end you see it move . worth watch in the dark for the very creepy climax . kudos for the director long take and gil ( andromeda strain ) melle unsettle score .
