It's great that so many of you like Faramir so much!
Yes - the description of his awakening to life is very moving. I also think that that scene has a very profound symbolic meaning. Faramir and Aragorn are still rivals - they both have lawful claims to rule Minas Tirith, Faramir as the Heir of Denethor, Aragorn as the Heir of Elendil himself. And Aragorn does not win by defeating Faramir (= demonstrating that Faramir is weaker, less worthy...) - but by healing him, by giving him new life. The righteous King is the Healer, the Giver of Life - and not of Death.
However, I felt a little bit disappointed by a brief account of the meeting between Aragorn and Faramir after Aragorn became the King; it was too much cold and formal for me. I expected that they will become personal friends... like Aragorn and Eomer. ..
As for the attitude of Denethor - I can understand it very well. Finally the choice of Faramir proved to be juistified - but it could very easily prove to be totally disastrous. Denethor was convinced that the quest of Frodo cannot succeed and that it will only hasten the moment, when the Ring will fall into the hands of the Enemy. And it's true alas what he said to Faramir, that he made his choice not only for himself, but also for his whole people, whom he should protect... without even asking them their opinion. Finally some of them could prefer thraldom (with the hope that it won't continue infinitely!...) to the ultimate destruction of Gondor.
In a way, both Denethor and Faramir were right. And it's this that makes their relationship tragic. Denethor was not simply a nasty dad unjust to his son! Ttheir confilnct reminds me of the confilct between Antigona and Creon in the classical Greek play of Sofocles...
