The best scenes in "Just Friends" take place offscreen. If they were in the movie, they would involve the makeover of Chris, the hero. As the film opens, he is a fat, unpopular nerd in high school. Flash-forward 10 years, and he is thin, fit, rich, handsome and working in the music industry. Obviously, during the missing decade, he hired Oprah's trainer and studied the self-help tapes sold by that guy on late-night TV you know, the guy who will make you into a person willing to accept success. You have to be willing, that's the trick. The guy's methods are proven because he is a success himself, having been willing to make millions by selling his tapes.
