Take Shelter (2011)

Plagued by a series of apocalyptic visions, a young husband and father questions whether to shelter his family from a coming storm, or from himself.

The movie has atmosphere and a good cast, but the whole story is based on the question "Is this only in his imagination?" so that the last scene is predictably the answer to that question, and there are only 2 options: yes or no.

Maltin**1/2: "Writer-director Nichols' original story is nuanced and never less than interesting, but the combination of slow pacing and a palpable feeling of dread makes it a tough sit. Shannon, who often plays creepy characters, is terrific here as an ordinary guy going through an extraordinary experience."
