Radio serials have been my favorite format of media ever since I listened to all of the Hitchhiker's Guide to the Galaxy. They are like the best parts of audiobooks combined with the best parts of film or television.
I really liked the books, but I have to agree with you there. Even series 3-5, which followed the books instead of preceeding them, were superior in radio format I think. (Particularly the conclusion to the series)
