Most sports documentaries tend to be full of tired clichés and repetitive themes that can leave much to be desired for a viewer. Television shows such as “Friday Night Lights” and HBO’s “HardKnocks” seek to provide an inside look into the lives and struggles that those associated with the world of football endure. While the human drama that ensues in both shows proves that football doesn’t always provide a fairy tale ending, the viewer is slightly influenced to believe that everything just might turn out okay.
