Narrative

In films the plot and conversations between characters is essential to making a good movie, if the dialogue is sloppy or the plot is bad, the audience may lose interest in what is happening in the film and what is going on. There are ways in which that you can create more excitement in an audience.
You can create alot of questions for example for the audiences in order to make them interested in what is happening and wonder what certain things have to do with the film. this is an example of how a simple device can improve a film dramatically by making the audience interested in it.
A plot has to have many characters and ideas to it if you are looking to make the film a deeper experience for the audience to view, and by linking them to the story , it can create a better movie, an example of simultaneous storylines branching from a main film is the departed, which has many main characters revolving around a story with many branch stories.
