premise: Tangled is an audio book.
hypothesis: Tangled is a 2010 American 3D computer-animated musical fantasy-comedy film produced by Walt Disney Animation Studios and released by Walt Disney Pictures . Loosely based on the German fairy tale `` Rapunzel '' in the collection of folk tales published by the Brothers Grimm , it is the 50th Disney animated feature film . Tangled spent six years in production at a cost that has been estimated at $ 260 million , which if accurate , would make it the most expensive animated film ever made and the fifth most-expensive film of all time . The film employed a unique artistic style by blending together features of computer-generated imagery ( CGI ) and traditional animation while using non-photorealistic rendering to create the impression of a painting . The film was well received by critics and audiences alike .
