I'm not in ignorance of the novels and the differences. However, Conan the Barbarian is an epic piece and defined sword and sorcery in the early 80s. It has a very definite energy and atmosphere which is not easily replicated. The sequel utterly failed to capture the same thing, and the reboot didn't even try.
There's a lot below the surface, and I'm not the first to say as much.
Conan the Barbarian and Psychoanalysis.
That's just one viewpoint. I've read others, but I can't find them easily at the moment, which go into more detail, or talk about Conan (man) killing Thulsa Doom (God) and replacing him. The film, despite its flaws, speaks to people on many levels, and specifically men.
So the point remains, for a woman to successfully write a sequel to this film, it would be rather surprising. Writing is directed by individual thought patterns, and it takes a considerable amount of self control, introspection, and empathy to write someone who isn't anything at all like yourself, especially if that person is amoral by your standards.
