What do you think about Paul Atreides? Jedi Master? Spoiled Child?
The Lynch version -
Too tall, but mature, steady, respectful. Very true to the book.
The Sci-Fi version -
Whiny. Very whiny. In the book there's a pivotal scene where he's told to fight - he says he's not in the mood - and is taken to task for his insolence. In the movie, when he petulantly says he won't fight, his teacher says "Oh ok".
Paul was supposed to have an adult's maturity and rational, even while young, because he never had children playmates. He had been trained to be a leader, trained as a mentat, trained as a BG and a soldier. He was supposed to have respect for the wisdom of his elders.
