Zeitgeist is a movie series that tries to explain complex topics in a simple way. The movies talk about how the world is changing and how everything is connected to each other. They explain things like why people are unhappy with the government, why some people are poor and others are rich, and how religion affects the world. They also talk about how history repeats itself and how things we do now will affect the future. The movies use lots of pictures and videos to help people understand what they are talking about. They want people to think about what they see and to ask questions about why things are the way they are.
