Really, it's because these stories distill so much of what's compelling about drama into a tight-knit package. To wit: films about competitive fighters carry the connotations of the sports movie, yet are about the individual and not the team. They take a look at people who want to either better themselves or conquer their opponents, as well as everything in between. That's exactly what Benny Safdie's latest film, "The Smashing Machine," is punching towards. In the way in which Safdie makes the film a reflection of real life's mercurial morality, "The Smashing Machine" packs a subversive punch.
