I posted most of the following in another message board, where Chapter 3 and the encounter with Gildor were being discussed, but I'd like to delve more deeply into the subject of elves, both in the Book and the Movie. There are so many conflicting images of them in both.

Now the elves ... (gets a wistful, Samwise expression).
It's hard to imagine how someone would feel who is over 1000 years old and still in the health and strength of youth, and has seen so much. We poor mortals must trade wisdom for energy, growing feebler and more circumspect as we age. We both grow and die a tiny bit each day. We eventually tire of a life in which we can no longer fully participate. But would we tire of it if we still had youthful bodies?
I've always been struck by the way the elves (except Legolas and Arwen) are indifferent to mortal folk. On the one hand, we would seem so fleeting to them, and our problems so transient. Our short-term tempestuous relationships are hard enough for us to live through - imagine having that speeded up by a factor of 10 or 20 (as it would seem to the elves) and blinking in and out of existance. {Imagine reading 20,000 pages of "The Paths of the Dead - The Fallen From TORC."} But on the other hand, would they find us a momentary diversion in their incredibly long and repetitious lives? Would they still have a zest for exploration and learning, or would they eventually fail to find anything new under the sun? Would they all be detached and bored, even as they "made merry"? What would be the point of each new day?
What kind of wisdom and attitude would elves have after a 1000 years? Would self-centered and immature elves finally see the futility in self-agrandizement and self-indulgence, or would they have simply taken it to new extremes? Tolkien wanted his elves to be of higher quality than humans, so perhaps there were no immature elves (except for the first few years of their lives).
Elves do not age, so what level of maturity are they "stuck" in? The wood elves in The Hobbit seemed rather childish (I'd go so far as to say bratty). But Gildor's high elves seemed mentally in their 40s or 50s and physically more in their twenties. Legolas seems like a man in his 20s. He does not show the wisdom of his age (especially in the Movie).
