Wow - I have just stumbled on this fantastic quote about Tolkien from China Mieville (via GR friends Traveller and Cecily!) and it absolutely sums up the problem with Tolkien - even though I read him many years ago and even though I was enthralled and read him all over again, every word here is true : 
 "Tolkien is the wen on the arse of fantasy literature. His oeuvre is massive and contagious - you can't ignore it, so don't even try. The best you can do is consciously try to lance the boil. And there's a lot to dislike - his cod-Wagnerian pomposity, his boys-own-adventure glorying in war, his small-minded and reactionary love for hierarchical status-quos, his belief in absolute morality that blurs moral and political complexity. Tolkien's cliches - elves 'n' dwarfs 'n' magic rings - have spread like viruses. He wrote that the function of fantasy was 'consolation', thereby making it an article of policy that a fantasy writer should mollycoddle the reader. 
 That is a revolting idea, and one, thankfully, that plenty of fantasists have ignored. From the Surrealists through the pulps - via Mervyn Peake and Mikhael Bulgakov and Stefan Grabinski and Bruno Schulz and Michael Moorcock and M. John Harrison and I could go on - the best writers have used the fantastic aesthetic precisely to challenge, to alienate, to subvert and undermine expectations."
