We do have a great tradition of fantasy & SF writers, I have to admit. Growing up in Britain, you just regard it as another available reading option and make up your own mind.
The Hobbit hooked me, IIRC, and I haven't looked back <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
The US has many fine fantasy writers too, though IMO the top two current fantasy writers are both British - Terry Pratchett and David Gemmell. Both are unique and extremely talented writers. Which is best depends on my mood though, I must admit, as their writing styles are very, very different.
