Have you looked at Ana Mardoll's Narnia deconstructions? (The link format went funny, so that link may not work. A Google search for Ana Mardoll will most likely find her blog.)

She's done The Lion, the Witch and the Wardrobe and Prince Caspian and is currently working on The Voyage of the Dawn Treader. I find her analysis very interesting. She's pulling out a lot of stuff that I never thought was in there but that I'm enjoying thinking about. I do have a childhood attachment to the books (and I've written fic for them), but that doesn't mean that I'm not interested in seeing the problematic stuff called out.
