There ARE so many great Howard stories, but the main reason they won't use them is that is not how Hollywood works. Movies get made to a template; they are rarely faithful to the original story. So all these movies, it doesn't matter what powers the character has or how he acts, they always end up the same way with pyrotechnics and the two main protagonists having a punch-up. A case in point wsa the Solomon Kane movie. They had a great opportunity there to do something really different: a puritan! but a swashbuckler! And it just ended up it could have been about anyone.
