The movie was a perfect adaptation for the novel. It was truly faithful to the book, despite a few minor editings. Sure, they left out some things, but they were not important. The added lake scene was a great addition, in my opinion. The movie truly captured the air and beauty of Narnia, and every time I watch the movie, I feel like I am really there, next to the Pevensies. The special effects were mind-boggling, what with the perfectly-real Aslan and all those creatures. The score perfectly tied in with all the different scenes, and it really held the movie together. There isn't really much to look down on in this movie, although the voice of Aslan didn't really appeal to me. It didn't seem to be as majestic as I had imagined.
Overall, however, this movie is absolutely fantastic. The humor, beauty, and emotion of the movie really tie together perfectly, and the movie has much replay value in my opinion. I loved it!
