“Pete’s Dragon” is a movie I hadn’t seen since childhood. I remember being terrified of Shelly Winters, covered in all that mud, and bored by the Helen Reddy boyfriend-lost-at-sea subplot. But when my friend Chris Dufault stated recently that “Pete’s Dragon” is one of his favorite movies, I felt a sudden need to see it again. And so we made a “Pete’s Dragon night”: Chris would bring the DVD and his boyfriend Jonathan and I’d cook something appropriate that’d complement the viewing experience. What would that be? Why leg of dra…I mean lamb, of course!
