Is “10 Cloverfield Lane” a sequel to the clever 2008 monster movie “Cloverfield”? I’m not telling.

The point of this precisely crafted film is psychological possibility. It creates a kind of Hitchcockian thriller where uncertainty soaks the story and spreads like blood on a shirt.

The crisis here isn’t mass disaster. A woman jolts awake locked in a basement bunker, where a survivalist says he has rescued her from a cataclysmic attack. But is he telling the truth?
