There are recent examples of stories and movies with non-human main characters, such as WALL-E and Monster. The author of Monster, A. Lee Martinez, pleads for more stories that are from a non-human perspective. This was covered by IO9 in shorter form, but with a nice Martinez book cover.

Martinez gets why visual media has pretty faces, but doesn't see why this is carried over into print media. (Maybe it is because many movies are based on books?). Says Martinez:

I’ve enjoyed sub-standard entertainment far more than I should because of a pretty face.

And:

A big reason I don’t read much fantasy / sci fi is because I want the weirdness, the monsters, the inhuman, and for the most part, that stuff is shuffled to the side. Almost all fantasy / sci fi is from the human perspective because almost all of it is aimed at a human audience.

I suppose Terminator is the philosophical dividing line, because the robot and humans had about equal interest in the story.

Bonus: the top 85 robot movies. WARNING: some movies may contain humans. Ew.
