Narnia film stirs controversy over Christianity

I'm not sure why there's any controversy over this movie. I'm not the slightest bit religous, and I'm really looking forward to it, because it's a great story. I read all these books several times when I was a kid, and really didn't even notice the religous parallels until the last book, where it was a lot less subtle. Anyway, regardless of how much religion is or isn't in these books, they're entertaining stories which is all I really look for in a book or a movie. I'd only be offended by a story being too religous if it also sucks, like that Left Behind crap.
