William Kunstler was a great lawyer and when I say was, it is because that is what the story/documentary tells us, it is told by his own daughter and she gives a really good and loving memory of her father in his great days.
But she also tells the story of a man that loves the lime-light and the attention that he was getting from the media. He loved his worked, maybe more then his family at times, and he was very passionate about standing up for his believes and the wrong-doing of those with power towards the ones they could oppress.
It is interesting to watch this media person and how he uses the media and court room like a theater and spins them in his direction.
