Perhaps my view on this documentary is a bit jaded. I waited for a few years until I was able to find a copy of it at a local pawn shop. Having heard it touted as "Hoop Dreams" but for football, I was sold. What I saw was not worthy of this reference at all...
I've seen nearly every commercial documentary about football, and pretty close to every football movie there is as well and this one simply doesn't hold up. The main figures are forced and come off as fake. The situations that come across in the movie at times look staged and or more gritty for the sake of being gritty. Over all, the experience feels less than sincere and more like something an amateur would make as a high school film project.
There are far better documentaries about this great game that would grab your attention and pull at your heart strings far more than this disappointment of a movie (Undefeated, and the sublime Go Tigers!).
Save yourself the time and find another documentary to watch.
