When I walked into the theater, I was afraid they wouldn't follow the book at all. But as I watched it, I saw that they followed it page by page. I definitely suggest reading the book first though. There was actually one time where I yelled "Yes!". After Aslan roared after being brought back to life, it was great. The sets were beautiful, the actors were above average, and the only changes from the book were improvements. You think the kids are gonna be just some wooden child actor, but they were so believable. The animals were very realistic and the entire movie was just fantastic. I recommend this movie to everyone. Go see it now.
