My husband and I saw the movie this weekend; he got free tickets at work. I can't say that we would have paid full price to see it otherwise. I loved the visuals; the school scenes were fabulous. I loved the colours, the feel of the place. I have always had a thing for old creepy castles and this was lots of fun to watch.
However, the story line made absolutely no sense to me. It just irritates me when authors succomb to the old "I need a plot so let's find a complicated answer to an easy problem". For a good plot, I would have much prefered to see the Narnia Chronicles on film!
Nevertheless, fun viewing it is, and you might even be able to catch a nap somewhere in the middle.
