Nothing is as simple as it seems!!!

Whenever I went to the movie with my friend, seeing special effects, the story, the characters of the film....but most of all, to sometimes learn more about the film through the word of the narrator. However, after reading Bordwell and Thompson - Narrative as Formal System, it opened up to me a whole new perspective: Nothing is as simple as it seems to be!!! Through the reading, I am now understand just how much vast the narration field is! But, the thing I am still need discussing about is the fact that there are so much information, so much knowledge in just one field (For example, in narration field, there are nondiegetic material, the following of the story flow, the logical of the plot, the parallelism technique, the perceptual subjectivity, the mental subjectivity...), but bringing in too much could make the film a little bit confusing sometimes don't you think? In my opinion, I particularly like the concept of the parallelism technique, the perceptual subjectivity, the mental subjectivity. But if we are to shoot a short film at an amateur level, it would be really hard to put those concept into the film because it would make the film rather non-logical at some point or rather too confusing to understand. Any one have any other idea, please tell me, I am very eager to learn ^^.
