What book/movie/song changed my perspective

I would have to say alot of movies change the way I look at things. It also depends on the type of movies, Im not talking about comedy or horror, but actual biographies. Movies that focus on tragities or ones that point out flaws in our society. I think they change my perspective because I know about most of them I just choose not to notice, but when a movie comes out Im forced to accept the reality and learn from it or criticize it. Movies have the most impact because it can also show me what others are doing to change this and I can always jump on the bandwagon.
