I'd be worried if Harry Potter was replacing Holden, but the two can stand proudly side-by-side. The alienation in Harry Potter may not be as overwhelming as it is in Catcher, but it's probably even more pervasive in how it illustrates the world as a relatively amoral place where few people care about others for the sake of caring. The Goblet of Fire marked a moment when a whole generation of kids suddenly got a lot older.
