Documentary that tells the story of the often-contentious development of both preventionist and interventionist technology in the cardiology world over the last 60 years, highlighting the ongoing battles between insurance companies, the American Heart Association, groups of doctors, inventors, and financiers, all who have a vested and monetary interest in their pet technology gaining the most traction. The Widowmaker is a disheartening portrait of blatant greed, as well as a fascinating examination of the trial and error process used in the scientific method. It does what good documentaries should do: it shines a very focused light on a very specific problem, a problem that affects millions of people and their families. However, it is not a grab the popcorn and enjoy a movie film. Best suited for educational purposes.
