About bloody time.
It isn't half bad: neutral, accurate enough. Good job.
So far, the only actual REH adaptations I see on the page are the HPLHS's "Casonetto's Last Song," and Thriller's "Pigeons from Hell." Obviously I'm not counting the theatrical films, because I walk the line between angry young man and ornery old coot. I would happily include "The Return of Sir Richard Grenville" and "Cimmeria" on that list, even if they aren't quite on the same production scale as "The Hunt for Gollum" or "Born of Hope." Better adaptations, though.
Comics is fine, though it clearly needs further expansion. There is one glaring omission: Richard Corben's Bloodstar, an adaptation of "The Valley of the Worm" in all but name. I think a mention of the first graphic novel to refer to itself as such is worth a mention. There should also be mention of Kull, and the the various non-Conan/Kane Savage Sword adaptations.
Music seems to be the most comprehensive, with plenty of Manilla Road's discography, as well as Domine, Bal-Sagoth, Cauldron Born, Mad Minstrel and Rosae Crucis. The Sword's "Black River" should get a mention, as it's had quite a lot of popularity since appearing in Guitar Hero: Metallica. Man, what I wouldn't give for Manilla Road to do a whole Howard concept album...
