There's a reason junior high teachers believe they can make pre teens care about Shakespeare?by giving them Romeo and Juliet to read. It's an engrossing piece of literature with a timeless story of undying love.
If you weren't forced to read it as a kid, I recommend reading it now, there's plenty of reasons it's inspired people for hundreds of years. Not everyone would agree though, as Samuel Peyps, of the famous diary once wrote “it is a play of itself the worst that I ever heard in my life.”
Franco Zeffirelli's film adaptation is a great accompaniment, though I might be out of date. These days kids are all about the Baz Lurhmann, Leonardo DiCaprio version, or more likely, High School Musical, which takes plot cues from the eternal popular play.
