It"s easy to see why You"re a Good Man, Charlie Brown is so popular. With its simple set and small cast, it has become a staple of high-school drama and small-scale productions all over America. Of course, this doesn"t necessarily translate into a grandiose Broadway show, but this Michael Mayer-directed production is enjoyable. Anthony Rapp (Rent) plays an effective Charlie and Ilana Levine"s Lucy is fun. The lively "Snoopy" number (Roger Bart plays the canine"s role) is the musical"s highlight, but such tunes as "Beethoven Day" really date the musical. Some may find it simplistic; others will love it. Which probably makes it a lot like the "Peanuts" comic strip itself. --Jason Verlinde
