These rants are well worth a look. Lymyaael covers everything from back stories to dragons to teenage runaways to gay stereotpyes to final battles--and why not every fantasy novel has to end with one. Fun, insightful stuff!
(Some of these rants are also listed here. I plan on checking both links periodically.)
I stumbled on these rants via the Notebook in Hand forums; a lovely place for artists of all types. Enjoy!
