This low-budget horror-mystery is a "secret" spin-off of the J.J. Abrams-produced giant monster movie Cloverfield. John Goodman plays a survivalist who rescues a young woman (Mary Elizabeth Winstead) and stashes her away in his underground bunker. But is the world really coming to an end, or is he just a crazy dude? (Given that this is a sequel to Cloverfield, the surprise ending probably isn't much of a surprise.) 105 minutes PG-13.
