Humanities topics usually want the MLA ( Modern Language Association ) style. Soft sciences and social sciences prefer the APA ( American Psychological Association ) format. Biology and life sciences use the NLM ( National Library of Medicine ) style guide. The more comprehensive Chicago Manual is specific to American English and also covers grammar and punctuation. Even the AMA ( American Bar Association ) have their own formats. Writing experience counts when grades depend on a formatted citation. After all, this sort of detail requires time and effort to understand and apply.
Sometimes it is easier to watch a movie rather than read the book. Some movies that are adaptations of books can enhance the setting, the scenery and dialogue. This is especially helpful for people who have experienced difficulty in learning to read, as watching the movie as well as reading the book can enhance the experience. A movie adaptation can enhance the experience of the book and can bring to life, and get transported into 'this other world'. Visual images are very powerful, but so is the experience of reading and development of our own images. It can also be argued that in order to use our imagination whilst reading we need to have some actual experience of the situation and that experience either comes through accurate and informative writing or visual images (movies).
