A Good Marriage: That's what she thinks

Joan Allen & Anthony LaPaglia

This 2014 movie on Amazon is based on a book by Stephen King. So far, so good.

Darcy and Bob have been married for more than two decades and by all indications it's a good marriage. Until...

Without issuing a spoiler alert, the Movie Slut will say that Darcy discovers something that reveals hubby isn't the guy she thought he was. In fact, he might be—Eeeeee!—a serial killer.

What should she do? And who's the mysterious man lurking outside her house? Is he the real murderer? Is she in danger!?!

The Movie Slut is glad she stumbled on this thriller while remoting through Amazon's selections. There's something comforting in getting freaked out by a movie monster rather than a terrifying real life event.
