It's why Aragorn's almost paralyzing self-doubt works so well in the Jackson films even though it's nowhere near that dramatic in the books. Jackson and Co's choice to do this was intentional, not negligent, and it worked. Whether we agree with their choices or not, the films and their characters still hold up on their own to this day.
Ehhh....I agree that was a deliberate choice, but I really hated it. Giving Aragorn lines like 'the same weakness flows in my veins' was painful to hear.
I get your point, about taking it and running with it so that it's clear to the audience, hey, elves and men are different! But...this was *not* a decision I agree with or admire in any way. I would not like to copy that aspect of Jackson's work at all.
(I do agree with your point about story-telling in this medium, just...not the example.)
