This is an excellent, and faithful adaptation of the book by Jack London. Be warned. If you love, CGI, and endless action and fight scenes, this is not the move for you. The movie itself is beautifully shot, no CGI screens, all shot on the watet. The cinematography is one of the stars of this movie. It makes me long for a time when movies were shot on location, versus CGI. As mentioned, it's a faithful adaptation of the book. The movie focus on two characters, Captain Wolf and Humphrey. Through the journey, we see the best and worst of humanity as the cruel and sadistic Captain Wolf is countered by the humanity of Humphrey. Do yourself a favor and watch this.
