As a cyclist, loved the opportunity to see a cycling-related movie. Many people (both cyclists and non-cyclists) can relate to the human struggle to achieve the seemingly impossible and thus, this movie had broad audience appeal.
I understand the commercial value in making Lance Armstrong the center focus, but I would have more liked to see more about 'mere mortals' and their stories and challenge. Though understated, it did show the difference between the humble, gracious nature of 6 time Leadville champion David Weins and the overhyped, entourage-touting style of Lance Armstrong.
