Unreliable Narrator

            I think in a story not have a good narrator, audiance will not be infection and they don't think this story deserve to see.Write a narrator is very difficult, because in narrator can't performance more than important drama, and must make audiance exciting. 
            A unreliable narrator could be make audiance boring and tidious. And audiance won't  trust this narrator, or don't want to see this story.But we can trust 80％ story narrator, so we just see this story good or bad, don't worried about others things.
