The LW&W was one of my favorite books as a kid and I was excited when the movie came out.
I can't put my finger on it, but unlike the book, I didn't "feel an attachment" to Aslan's character, nor was his sacrifice scene as terrifying as it was in the book. I remember sobbing when I read the book, but not one tear in the movie.
Maybe it's just because I'm old now.
As for Christian themed movies, I would certainly include the moralistic Irwin Allen disaster movies of the early 70's.
Remember the 'Jeremiah' scene where Gene Hackman is pleading with them to come with him out of the ballroom and they angrily refuse ? And drown like rats in punishment.
I don't think "The Da Vinci Code" is going to be high on the list for most conservative Christians. The church I attended did a 3-week series on the various flaws in the book.
