To anyone born before 1975, the name Ralph Nader means something far different than it does to those who have been born since.
To those younger audiences (of which I am a member), Nader is best known for his presidential campaigns and, according to some pundits, being responsible for Al Gore's loss to George W. Bush in 2000 by fracturing the liberal base.
So it's notable that An Unreasonable Man moves through Nader's life chronologically, holding off on discussing the 2000 and 2004 elections until the every end.
For many, it's an education in Nader that is sorely needed.
