I feel sorry for the 16-year-old girls who chose to see “The Words” that weekend back in 2012 when “House at the End of the Street” was sold out. (“Let’s just see that thing with Bradley Cooper. OMG! He’s so gorgeous!”) Figuring out this film is a lot harder than any of the politically correct cryptofiction they’re force fed in their high school American lit classes. Hard, but good. It’s a story about a storyteller telling a story about a story. At the end, the movie gives you the finger and sends you off to figure it out for yourself.
