I don't know -- I think even a successful ensemble film has to pay close attention to POV within its various storylines. And your typical action movie doesn't have nearly so many important characters to handle. But leave that alone for now. I think it's interesting simply on the basis that the book is deliberately written from a very limited, hobbit point-of-view. I'm not arguing yet that Jackson's more omniscient point-of-view is necessarily good or bad -- just making an observation that we're a bit all over the map POV-wise so far, and wondering how this affects movie watchers who are fans of the books. Is this the reason, or one of the reasons, why you don't identify so closely with the hobbit characters?
EDIT: That's sort of a rhetorical question that you need not answer.
EDIT 2: Guess I hit "reply" before I'd really thought this one through. I'd also like to point out that I'm not saying that a limited point-of-view is better or worse than an omniscient point-of-view, just pointing out that it's an important choice, and different choices produce different effects in the audience. Hence, a skilled filmmaker will deliberately employ a POV, or shift POVs, to produce desired effects on the audience, whereas a sloppy shifting of POV may produce unintended effects. I can't say whether I'd argue one way or another in Jackson's case yet, just, again, making an observation. How does Jackson's use of POV here affect the storyline?
Erm, rhetorical question again...
