Interestingly enough I agree on most of the "Faramir points" with both Phantom and Scottomir:
Scottomir hits dead-on why Faramir is an interesting and pivotal character in LoTR: the man who shows that the race of men is worthy and true; the one person who is not even tempted by the ring. I would have preferred that Faramir told Frodo what he should have told him in the book.
On the other hand, Phantom has a point as well, Jackson has been playing up the rings corrupting influence in the movie far moreso than it was in the book. The Gandalf scenes after Bilbo's Birthday Party I think especially set that tone. When Frodo extends the ring to Aragorn near the end of Fellowship is another. They are playing that side of the ring up in order to dramatize something that is a very subtle point in Tolkien. Now, I disagree with the "how could a mere man stand up to the power of the ring" idea because that was what made the Faramir character so compelling in the book -- it was his one true and shining moment, and by extension the race of men.
Dramatizing the subtle nuiances of the book is the crux of the thing. Jackson already had the "Ring offered to human who turned it down" scene in Fellowship (true it was added) to have another in TT would have lessened its impact. Also, Jackson is trying to dramatize the dysfunctional relationship between Faramir, Boromir and Denethor and this is the best way to do so.
Once again, I would have liked Faramir's character to stick to the book. Especially since the "voiceover" ("video-over"? Cuts with Elrond and Galadriel) at that point in the movie is talking about how worthless humans are ("Ring? No thanks." Take that Fairy Bee-atch!). I liked the qualities of Faramir that Scottomir brought up. Nevertheless I can see how Jackson has shifted things in order to increase the impact of the story by way of a largely visual, and also rather truncated, medium.
p.s. On an unrelated note, show of hands for those who think Eowyn doesn't deserve Faramir (Faramir: "Allow me to show you every kindess and respect while I woo you." Eowyn: "Gosh, I can't have the man I really want so I guess I'll settle for you.") and that Faramir gets a raw deal politically too ("Gee Faramir, thanks to you and your entire line for taking care of things while there was no King in Gondor but I'm back now. By the way, can you live out the rest of your life in semi-exile in Ithilien? As a... reward for your... service." Yeah right.)
