A meaningful movie that might help in our grappling with evil in the wake of the tragedy in Newtown, CT, is M. Night Shamalyan's "The Village." The trailer below is actually very misleading (if you saw M. Night Shamalyan's "Sixth Sense," you know there's always a big twist). The movie is not a horror film, and is not even scary.
Horrific evil has been with us since Cain and Abel. There is no magic formula to insulate ourselves from it. But love is stronger than evil. Love is stronger than hate. Love is stronger than death. Love wins. Love always wins.
