While Take Shelter isn't by any means perfect - writer/director Jeff Nichols could use a refresher course on editing - it's a powerful film, displaying a devolvement into insanity that ultimately proves to be quite visionary.
As a director, Nichols creates such an intense aura of dread and impending apocalypse during the visions that when Curtis simply describes one that is not shown in the film, we shudder at the mental image it paints.
Michael Shannon is at his best as a man plagued by apocalyptic dreams that start to bleed into his everyday life. It's one of the best independent American films of the last decade, playing on current concerns about the future of the planet.
An intriguing, painful film about the angst that's currently in the air, about misreading the runes, about embarking on actions that might make us laughing stocks, about taking wagers with and against history.
