Did anybody else not like the "I am no man!" line? It seemed to be trying to like, score grrl power points or something to me.
The Clown's right, this is very much what Tolkien intended. I think it may actually have something to do with his dislike of Macbeth. In Shakespeare's play Macbeth supposedly cannot be killed by any man born of a woman. Eventually Macbeth is killed by some guy cut out of his mother's womb. Tolkien probably saw this as a huge cop-out and decided to do it right in ROTK. I thought the movie was awesome in how it handled it.
The Ents were also inspired in part by Tolkien's dissappointment with Macbeth but you knew that if you watched all the TT extra discs.
Let me also say that ROTK was truly Peter Jackson's Christmas gift to the world.
