THE STEPFATHER (1987)
Forget the forgettable new remake with Gossip Girl's Penn Badgley, you'll want to check out the original version of this bad boy for three reasons. First, it's an underrated Reagan-era classic. Second, it stars our favorite unsung Charlie's Angel, Shelley Hack. And third, it's not every day you get to see Lost's John Locke (Terry O'Quinn) as a psycho with a (relatively) full head of hair.
