I don't really know. I enjoy books, I enjoy TV and films. But I would never listen to radio plays or the like or even spoken-word versions of books. It's just not a format that I can imagine sitting down and listening to. I'd prefer to listen to music. That's not to take away from others' enjoyment of it; I can't really explain it any more than I can explain why I don't like broccoli!
I understand the feeling.
But you know what's weird? I love the
Doctor Who audio plays but I'm not at all interested in the novels. Yet I love the
Star Trek novels (well, declining over recent years, but I still love the old ones I read) but I really have no interest in
Star Trek in audio format (I don't have any interest in the one Sulu audio).
That being said, I was too young and not in the right place in my life during the so-called "Wilderness Years" when the
Doctor Who novels were really popular.
