I saw this documentary on Netflix, and noted that it was over three hours. My first thought was "How could you get a three hour documentary out of the Eagles?" After watching it I can say they absolutely filled three hours. It felt more like an hour and a half. The personalities involved are fascinating, and the inside story of what was going on through the ten years of their heyday makes for great watching, especially if you were around for it. Not to mention the music is awesome... and Joe Walsh is still a crazy man.
