Well when doing the movies, everyone focuses on the ones that include the Pevensies and Eustace. I would love to see Magician's Nephew and The Horse and His Boy done.

The Last Battle never really grabbed me. I think it was too much allegory. I don't have a problem with the Christian allegory, just allegory in general needs to be used carefully, and I think it was way overdone.

I thought the movie Prince Caspian was not very good. Caspian is supposed to be like, 12. They just kind of screwed with it to make it more dramatic

(OMG UNCLE'S BEDROOM YOU KILLED MY FATHER I KEEL YOUUUUU! bugged the hell out of me.)
which just irritates me. Money over art, eesh.
