    在動畫的世界里簡單的故事是絕對的要素,一個復雜的故事情節折迷離的環節對于看動畫的觀眾是一項極大的負擔,在現今的市場需求上趣味已經取代了傳統的故事鋪陳,在這個趣味掛帥的年代怎麼樣用簡單的故事來表現劇情變成了最重要的課題,很明確地,從影片廣告的方式可以感受到什麼樣的主題才是消費者的需求,過去高成本大製作的廣告模式這幾年已不復見,取而代之的是影片有多趣味多好玩,這就是典型的簡單故事描述復雜的劇情,舉例來說:電影史瑞克就是一個很典型的例子,單純的救公主的劇情,不斷的以「與傳統思維相」的劇情沖擊著觀眾的思考模式,我還記得當時看完該片后出場不斷的聽到眾人討論趣味的情節,但是卻沒有聽到半個人說這部戲的故事有多棒,其實這樣的劇本就是最好的動畫劇本,讓觀眾獲得他們想要的劇情卻不以復雜的故事包裝,這才是動畫編劇的最高境界,因為願意花錢進到戲院或是花錢購買dvd的消費者,都是想開開心心的觀賞影片沒有負擔、沒有包袱,也就是花錢買開心,特別要提醒的「寫作動畫劇本並不是寫給個人滿足己的創作慾望而是對所有欣賞的人群」 。
