You didn't get the movie .. and yet ... your icon is a big statue of Jesus?
I liked the movie, and kids liked the movie, and it was a good movie. I've read the books (when they came out, a looong time ago) so that helps. Others I know who had not read the books, also enjoyed the movie.
Lewis has a good take on Christianity in my opinion, far more focused on being good, doing good, being true, rather than dogma. Especially in The Last Battle.
Lots of interesting things in the books and movies to delight the young.
The beavers were great in the movie, very funny. Lots of funny bits.
Don't know why you are comparing to LOTR. Very different. Wish they'd make Silmarilian, now THAT was a great story. (precedes LOTR).
