1. The hideous change of expression in Bilbo's face as he grasps for the ring at Rivendell was totally unnecessary. The torment of Bilbo's soul was already apparent. By that time in the movie it seemed obvious that the ring had an evil influence on men's (and hobbitt's) souls.
2. There were several places where the movie "lied to us". The scene in the mines of Moria where it looked as though Frodo had breathed his last, only to learn moments later that nothing had really seriously happened to him at all.
3. When Galadriel was offered the ring, the physical change that took place was goofy. The same holds true for the parts of the film when Frodo put the ring on. Apart from the initial unveiling of the Ringwraiths, subsequent scenes got pretty old.
4. If that's New Zealand, then I'm moving. What a gorgeous place! ( I say this realizing some of the scenes were mixed.)
5. The huge stone gate figures on the lake were awesome.
6. Liv Tyler is a doll despite having a loser for a dad.
That scene is straight from the book. I believe Aragorn actually carries Frodo for a while believing him dead.
I agree about the change in Galadriel. The words were right, but as I recall she was beautiful and terrible, not demon-ghost-like.
The visualization of what Frodo sees when he wears the ring was good and important. I do recall that putting on the ring made him part of another world, with only dark images of the real world. It also explains through example why the riders could not see him better when he was NOT wearing it, because they see the same thing wearing their rings, relying instead on half-blinded instinct and the "sniffing".
