I do not disagree with you. This is obviously happening on many levels. I do, however, believe it's important to notice that this tool of entertainment is also used quite often to wake people up and get them thinking. I don't have time to list all the movies/ shows/ music I think provides this as well, but as you said, there is a pendulem, and there are people creating from all angles. I've actually been equally impressed with how many consciousness awakening productions are rising to the mainstream recently as well.
