May not be the best at writing his own plays, but damn, the guy can teach. He keeps the class small (priority to majors and older folks) and he dedicates time to each student and their work. You will be a better writer after your time with him. He limits the number of people who take both his courses, especially consecutively, as he likes you to get a larger array of perspectives from other professors. That said, the two courses are just different enough that you can take them and get something out of both. He's easily one of my favorites.
