A must watch movie. Some great performances that back up the message. Yes, a huge and weighty subject, but wrapped up and delivered within a thoroughly watchable and entertaining film. The sad sad thing is that while you’re watching a 70’s historical piece you put the issues into perspective of the time, then fast-forward to current events in the US and it becomes sadly depressingly obvious that this is not history, but now, right now, and all too real... But for all the subject matter this is a very good movie, entertaining and thought provoking in equal amounts. You will not feel short changed. Go see it, as soon as you can.
