Yeah. I think it also has to do with the age at which one gets exposed. There's a window during which the right person will bond to the right book very strongly.Fair play! I think it has a lot to do with the writers style - and the reader's personal taste. While I never really got on with Tolkien I love a lot of the fantasy that is fairly obviously derived from his work.
The greatest enigma for me is Stephen King! Technically he writes very well, his dialogue is great, characters well developed, and plot lines interesting and novel. Yet, I really don't get on with his books...slogged through a few and can't really say I enjoyed them. His book "On Writing" is a fascinating look into the writers craft, a really wonderful book. I just can't get on with his fiction, for some reason I have yet to really identify!
King never did it for me. His novels bore me to distraction, though I have read one or two short stories of his that I thought were effective.
