Let's face it, Tolkien wasn't much of a promoter of women's equality (to say the least). Thus there are no female characters in the Hobbit. the Lord of the Rings certainly has several (Eowyn, Galadriel, Arwen, Goldberry...) but that is within a multitude of male characters.
Now, there's a commonly used test for a film being disregarding of women's lives and place in society, called the Bechdel Test. A film passes the test if:
- It has to have at least two [named] women in it,
- Who talk to each other
- About something besides a man
Seems like a pretty lenient criterion, right? Well, not really. It so happens that innumerable films fail it quite. It is somewhat less fitting for prose, since an author can write in the voice of a female character, describing her inner world, thoughts and feelings, even if she doesn't meet other women or talk to them.
