There are two kinds of books and movies (in very simplified example) - which are the art, and which are just a stuff for sale. The first ones are good for you, because they are altering you in good way. The second are annoying and damaging you like primitive direct advertisements (some kind of hypnosis). The first ones is the fresh food for your imagination, the second one is some kind of poison. Just make your choice what to see, read, eat, or drink. =)
