No, Rictor. Its Christian allegory, and it rocks beyond belief. In The Lion, The Witch, and the Wardrobe, C.S. Lewis essentially retells the Passion. Interestingly, he gets the story closer to Biblical accuracy than Gibson, since he dwells on the Resurrection and not the crucifiction (entabulation, I guess would be the right word for LWW).
While there is certainly a bit of Harry Potter (English public school children, in the English sense of 'public', meaning 'private'), and more than a bit of the numinous as found in the Lord of the Rings, The Chronicles of Narnia are almost entirely different in scope and character than either of those other fictional worlds. You owe it to yourself to give the books a thorough reading.
