30 NIGHTS OF NIGHT, Night 3: THE HARVEST (2013)

John McNaughton doesn't make films so often anymore, so any release of his is usually worth more than a cursory glance, especially since he's one of those directors like Alan Parker or James Mangold who refuse to be pigeonholed into one genre.  He started with possibly the most brutal serial killer film ever made (Henry: Portrait of a Serial Killer), went on to make a wacky splatter comedy in which an alien occupies human bodies and makes their heads explode (The Borrower), then followed with a dark comedy (Mad Dog and Glory) and a twisty-turny noir thriller (Wild Things).  Other than some selected TV work, that's about it.

With The Harvest he returns to horror, but not the ruthless terror of Henry or the goofiness of The Borrower; rather, he shoots for a more sentimental, tragic horror.  It is a story about two monsters who have become monsters out of necessity.  It should be no surprise that one of them is played by Michael Shannon, who is able to exude a single-minded amoral determination and utter helplessness at the same time.

Shannon is Richard and Samantha Morton is his wife Katherine.  She is a doctor and he has quit his job to spend more time with their son Andy (Charlie Tahan), who is ailing of an unspecified but debilitating disease which renders him barely able to walk.  It's getting worse.

Meanwhile, Maryann (Natasha Calis, of Possession) moves in next door with her grandparents and swiftly befriends Andy.  Trouble is that his parents--mostly Katherine--are suspicious about letting anyone get too close to Andy, and it becomes apparent that they're hiding something.

The first half of the film is brilliant.  The relationship between the two kids is charming and believable.  Morton takes a cue from Bette Davis and plays Katherine as a woman who might seem irrational and shrewish, but is hiding a desperation.  Shannon is her complement, a man who is sincerely devoted to his son but sadly doubtful that his efforts will save him.  There's a great Hitchcock-like sequence in which Maryann tries to sneak Andy out for a game of catch, the ending of which is somehow both surprising and inevitable.

Once the entire plot is revealed, the movie loses its way, especially when Morton stops being the overprotective mother and becomes a typical psychopath.  The transition is not quite as seamless as it should be.  Even though the movie never becomes nihilistic, it leaves us wishing it had gone a more thoughtful route.  It may have made a more effective one-hour TV episode than a full-length movie, but it's still worth a look for its two likable leads, and for Shannon.
