The Incomparable podcast features a bunch of serious geeks talking in alternate weeks about recent and classic sci-fi and fantasy movies, novels, comic books, and television shows. Our gang is led by Jason Snell, Macworld magazine's editorial director, and über-geek. The latest episode is available, covering Harry Potter, its borrowings from one Mr Tolkien, why Pablo Picasso and Magnum P.I. never met, and the words exegesis and tmesis.
