I was hesitant about this movie because I thought the CGI on the dogs would look too cheesey. I was wrong. It was not distracting at all, and I'm so glad I saw this film in the theater. While nowhere near as violent as Jack London's classic book, which was published in 1903, Disney did a great job of capturing the environment and emotions. Dog is man's best friend, and this movie had me wanting to book a trip to Alaska.
