Cons: 1) Pro UFC and almost exclusively about America 2) Biased against Japan. Completely ignores their significant role in the rise of MMA and a ridiculous characterization of legendary Japanese PRIDE and K-1 promotions as "infamous" 3) Unnecessary small segment with extreme injuries. MMA is a brutal sport but those kind of bone fractures and cuts are extremely rare 4) A bit dated. Can't fault the creators too much about it because films take 1-2 years to be released but the footage ends roughly two years ago which in the world of MMA is a lot 5) Somewhat too ambitious trying to cover the history, the current state, various personal story lines and more fringe topics like injuries
My recommendations 1) Casual person with zero relation to combat sports: Probably won't like it 2) Casual person with some relation to combat sports (someone who's trained one of the disciplines, someone who watches a bit of MMA or boxing): Worth a shot 3) MMA fan who's watched big events for some years: Will probably enjoy it as it's a quick tour through history and explores less talked aspects of MMA like training, mentality, injuries etc. 4) Hardcore fan who has watched many events for many years: Worth a watch. A lot of what is shown will already be known but there are a few interesting segments of important MMA figures like Gary Goodridge.
