I haven't read the book, but I have read outraged IMDb comments from fans of it. Some of the comments seem delusional, but there are some that sound like legitimate gripes. Certainly the ending is far too easy... not for children perhaps, but for me it felt cheap. And the pathology of the wicked headmistress is only hinted at, but never explored and as a result she just comes off like a one-dimensional evil bitch. But there's a lot of delight to be had in the movie. As with PRISONER OF AZKABAN, Cuaron demonstrates a masterful sense of style and ability to craft a tale that's enjoyable for the kids and also engaging for the grown-ups. The set design and color palette is gorgeous, and young Liesel Matthews is endearing in the lead. I also enjoyed the Indian flights of fancy and the general spirit of the thing. Despite some missteps, a charming little picture.
