I saw The Chronicles of Narnia: Prince Caspian on Sunday. I was a completely virgin viewer. Not only have I never seen the first Narnia movie, but I've never read anything by C. S. Lewis.
This is the ideal way to watch a movie that comes with loads of baggage. I had no way of knowing when the movie was making massive deviations from the book. I couldn't tell when a character came across quite differently from anything C. S. Lewis intended.
Instead, I just accepted everything as it came (Talking badger? Cool! Swordsmouse? Okay!!) and didn't worry about how it all fit together. Nothing like blissful ignorance.
I was vaguely aware that the movie series had some of C. S. Lewis' Christian symbolism. But if I hadn't already known that Lewis saw his Narnia as infused with Christian meaning, I'd probably have seen the religious aspects of the movie as Hollywood trying for a deeply spiritual meaning while still being vague enough to avoid offending anyone.
Miraz is the most wonderfully stereotypical Evil Overlord I've seen in a very long time. He is an utterly uncomplicated character. He has no eccentricities or odd character traits. He is simply an Evil Overlord. Period. I can respect that.
