When I was a long-haul truck driver I listened to this book, unabridged, on tape. Then I went out and bought the book, which I have revisited time and again. I am a Croup and Vandemar groupie!
I like the twisted fairytale bent Mr. Gaiman has. It's fun enough for older kids and savvy enough for adults. I would love to see a proper movie made, or even a "Nightmare Before Christmas" kind of treatment (not a musical, mind you, but the animation might be fantastic).
