Great look at what it takes to be one of the best fighters in the world. Frida's work ethic, talent, and power was obviously unrivaled at the time was on top of the sport. The doc shows all the dirty bits, harsh training, injuries, weight cutting... that fighters go through so much for a payday that may never be there. It's an unforgiving life. It's hard to warm up to Frida, though. She smiles maybe once or twice throughout the whole doc, and never laughs. The filmmakers go out of their way to show her as a mother to show her softer side: but she always comes across as distant, cold, or sullen. After the Prazak fight I found myself being sympathetic towards Diana instead of Frida, who won the biggest fight of her life only to worry and mourn for her opponents health. Loved the doc, though. Learned a lot about what happens behind the scenes.
