Several actors have previously taken on the role—Mickey O’Rourke in 2008 and Orlando Bloom more recently in “The Cut”—and now Dwayne Johnson has stepped up to portray UFC trailblazer Mark Kerr. The story unfolds during a period when he's able to support himself and his girlfriend, Dawn (Emily Blunt), though their lifestyle is far from extravagant. To achieve financial security, he needs to win the Grand Prix in Japan, which necessitates an intense training regimen focused on fitness and stamina. This journey is complicated by his reliance on substances that often leave him almost unresponsive. Problems arise at home as he struggles with his duties and must reassess what’s important before everything he has could disappear. The film is based on actual events, but I simply couldn't connect with it. Johnson does a good job portraying the friendly and committed athlete, yet a movie centered around a sport that required a rule change to prohibit eye gouging didn't seem destined for success in my eyes. The fight sequences are infrequent, sometimes intense, and they do illustrate just how violent mixed martial arts can be; however, the characters feel underdeveloped and fail to capture my interest. While Kerr appears to be a likable person, Blunt’s performance lacks significant presence as it progresses without much compelling dialogue to generate empathy. It does offer some amusing commentary on the absurdity of sports broadcasting, and I didn't dislike the film overall, but I doubt I will revisit it.
