I just read a whole National Geographic article on how Narnia was not about Christ, and they made a big deal about the mythological creatures such as minotaurs and satyrs.
I think liberals want to see it, and know it will be a big movie, so they have to find a way to convince themselves it isn't Christian.
The passion they attacked because it was too violent. (I remember one critic lamenting why do Christians go to see this movie, when there are so many better films about Christ like the "The Last Temptation of Christ"? Ha!)
This they know kids will want to see, so they are just going to pretend it isn't Christian at all.
Is there a link to the Nat'l Geographic article? If not, can you give the date and article title? Thanks. I'd like to ping a few dozen folks who wonder why it's significant to nail down Lewis' intent.
