He is simply a wonderful storyteller. Wouldn't be the same without him reading the story!
This is the book that made me love fantasy 50 years ago. I have read it more times than I can tell you and I read it to my son when he was 5 and it made him love fantasy too. Then, ten years ago or so, I listened to Rob Inglis read the book. So now I can say this is also the book that made me love recorded books. Rob Inglis is such a fantastic narrator- every hobbit, every dwarf, every elf has his own distinct voice and Inglis rich English voice adds to everything. This is one of those rare books that is actually better to listen to than it is to read. And, given how much I love this book, that's saying a lot. And the good news is- if you love the book you can then spend HOURS listening to The Lord of the Rings, which is equally good!
One final thing- the Hobbit movie (third part recently released) is a horrid bastardization of the book. It does have a Hobbit in it but that's about where the similarity ends. Tolkien must be rolling in his grave.
