Every movie or TV show is created to put a thought in your mind. None of them are made just to entertain. They all attempt to program the viewer with liberal ideas.
The story line is a tool to get you to watch, and to exercise a willing suspension of disbelief. You can’t watch it with a critical eye. You accept everything, so you will be entertained.
Your mind now has an opening. The producer pours his ideas into your mind, and doesn’t care if you notice.
You described mind control perfectly.
