I really enjoyed it. Although I found myself saying 'Ooh. That issue is much more complicated!' and constantly thinking of threads on the Downs.
I missed the last ten minutes, but I think I got the general idea of what they were saying. Although, they did seem to try and portray Peake as in some way superior to Tolkien. I doubt there would be many on these here forums who would say so.

But it is interesting to see how vast Tolkien's work is in comparison to others. The Silmarillion and the whole history of Middle Earth is something that really sets Tolkien apart from others. Its hard to find a world as fully developed as Middle Earth.
Tom Shippey is always fun to hear talk about Tolkien.
Also; Andrew Lang name check, very briefly. I was most pleased.
