Another Narnia reviewer, taken aback by the movie keeping Lewis’s God stuff in the movie:

What proves too uncomfortable at times, however, are the overt religious elements associated with the piece. Disney, the film’s distributor, would like to downplay those elements to a certain extent, but they are there and they are unmistakable. When a pivotal character is a lion — the king of beasts — and makes the ultimate sacrifice, only to be resurrected, there aren’t any other comparisons to be made, and given Lewis’ status as a leading writer of Christian thought, you can’t deny its existence.
