Selma - A well-told story which is a positive representation of what good can be done in the world, while at the same time being a negative representation of how horrible people can be to each other over something as unimportant as the color of one's skin.
A couple of thoughts: 1) At some point I should stop being surprised at how awful humans can be to each other, but somehow I am still surprised sometimes. 2) Even though the events in the movie happened over 50 years ago, the mentality of those (including politicians) who want to keep people down because of race has not changed that much.
