“The Hurt Business” (*** out of four) was a hard-hitting documentary about the rise of MMA fighting and how it has grown to be a lucrative international business but also film shows in frank detail about the brutal long-term damage (both emotionally and physically) it leads to for several former and current MMA fighters. Features interviews from stars Luke Adams, Ben Askren, and Josh Bartnett and is narrated by Kevin Costner. Film was made from the producers of “Bowling For Columbine” and “Fahrenheit 9/11” but bears similarity to Will Smith’s “Concussion” from last year. Not a great film but an interesting story of fighters who are aware of the dangers and consequences when they step in the ring but know no other way of life.
