Disney's animation has varied greatly lately, varying from such horrible animation as Atlantis, to the great animation of Beauty and the Beast. Even in comparison to the most recent disney film, Treasure Planet, Tarzan's animation is STILL much better than any other Disney film ever created. The studies of human anatomy are so amazing that if you look you can actually see that Glenn Keane and his team actually animated the character Tarzan from the bone up! The amount of work and money and time that has been put into this movie is quite apparent and makes the film ever that much more better.
While the comic relief characters of Terk and Tantaur are simply not needed (that role is taken by Porter), they do not totally detract from the movie's quality, as they seem to take very much a back seat through most of the movie. The character acting and animation is quite astonishing, as the animator John Ripa brings us through the feelings Tarzan goes through as a young boy coping with the harsh reality that he will never truly fit in with those he believes to be his family; as well as the feelings of love and understanding we find when the great master animator, Glen Keane puts his pencil to paper and helps us fall in love with Jane, and shed tears as we say goodbye to Kala, the ape mother of Tarzan.
Overall, Tarzan is an amazing film, the story, the characters, the backgrounds, and the animation are the best Disney has ever had since it's movie, Beauty and the Beast, and has only now been challenged by its latest movie Treasure Planet. I recommend this movie to anyone who has even the slightest appreciation for quality animation/film, as it ranks as one of the highest most well-done animated feature lenght films of all time.
