Also, I understand on an allegorical level why Aslan couldn't come save their butts again, but in terms of the story and the movie it was not well explained. He just kept saying the same thing can't happen twice. Well, so? Don't DIE again, but come roar and stuff! By the end, I kept thinking, why didn't Aslan just show up a couple of days earlier??? Now I am angry with him.
Aslan DID show up and save their butts again. That's my only complaint about these stories. The Deus ex Machina endings just kind of show me that no matter how bad the situation Lewis had to play what I always called the Storyteller God Card. Put your characters in a corner where the odds are ridiculously against them? No worries, because Lewis wants them to win, so he'll make it so that they do, regardless of how fantastical or illogical the device he uses to do it. He's the Storyteller, after all. It's his world to make or break.
That said, I fully enjoyed the stories and the movies. It's good entertainment, and I thought the movies were well done. But, as I said to my mother as we walked out of the movie theater..."Good movies, good books, but probably wouldn't get published today because of the contrived endings."
It just seems to me that the characters don't really earn their victories. In fact, they don't seem to win, or even be winning until Aslan, or some other entity, steps in and wins the day for them.
Oh, and the oldest two aren't in any more of the books that I recall. I don't think it was a slight against the actors...there just isn't more storyline for them.
