Ron: Just a question or two about your POV/Narrator point in film/video:
The camera cannot be non-biased, because it's operated by a human being.
Not only does this create bias, but the cenamatographer is directed to
shoot in a biased way.  Throw in the lighting persons ability to subtly
influence the way a sceen/actor comes across, and you've got a very
biased, if not schizophrenic, "narrator", don't you?
