Up until today I would have said that the best film I have ever seen was Exorcist the Beginning. It is the classic fallen hero story about a man who is forced by his convictions to stand up in the face of evil. However I have to say that the excellently complex yet simple story of a man named Edward R. Murrow who stood up to illuminate the abuses of the Communist witch hunts led by a 'Junior Senator from Wisconsin'
The thing that makes this story so powerful is the one telling fact that it did happen. It is a story about a dark time in our history and one of the men who stood up to it.
I strongly reccomend this film to anyone who wants to see a very well told story.
