电影的艺术表现媒介具有真实具体直观的特征,以照相为先天技术生成条件的“运动的声画影像”是物质现实的再现,这决定了电影的叙事机制或者故事本体,以及叙事结构,应该符合在物质现实中形成的一般现实逻辑。叙事机制和叙事结构都符合一般现实逻辑的真实影像系统,和拥有神话元素但故事本体符合一般现实逻辑的神话影像系统,二者都有生生不息的生命力,它们也是当今电影的主流。那些不符合一般现实逻辑的象征影像系统和特殊文化影像系统,还有那些叙事结构不符合一般现实逻辑的真实影像系统则是边缘,它们不能承担延续电影生命力的重任 The film’s artistic expression medium has the characteristics of true concrete and direct visualization. The “moving picture and sound of the movement”, which is based on the concept of photography as the innate technology, is a reproduction of the material reality, which determines the film’s narrative mechanism or story ontology as well as narrative structure, It should conform to the general real logic formed in the material reality. Both the narrative mechanism and the narrative structure are in conformity with the real logic system of the real image, and the mythological image system with the mythological elements but the story itself conforms to the general logic of reality. Both of them have vitality and are the mainstream of current films. Those symbolic video systems and special cultural video systems that do not conform to the general logic of reality and the real video systems whose narrative structures do not conform to the general logic of reality are marginalized and can not undertake the task of extending the vitality of the film
