Engaging and with great visuals! This animated film tries to convey the message that sometimes one just have to escape the boredom of a mechanical and dull life. The sisters seem to be feeling fed up with their lives and the flying book with its colorful creatures was a breather, an escape that offered another world beyond, a colorful world where one doesn't have to deal with rusts, metal, iron and the likes, symbolizing that of a repetitive and mechanical experience. Film scoring was also laudable!
