Paul Cooke says: "Michael Shannon gives a heart-breaking performance as a man who is plagued by apocalyptic visions during tornado season in small-town middle America. His family and work colleagues think he is losing his mind, and he questions his own sanity, but his sense of impending doom leads him to become obsessed with building an underground shelter in his back yard. Jeff Nichols mixes reality with fantasy to keep us unsure of our hero's state of mind until the very end."

*And we agree.
