Sydney Sweeney is quite compelling as a young woman navigating self-discovery while also possessing surprising strength. Playing Christy Salters, she must conceal her relationship with Rosie (Jess Gabor) from her mother, who is rather intense (Merritt Wever), as her fighting abilities draw the attention of a promoter recognizing her aggressive style. He sends her to trainer Jim Martin (Ben Foster). Initially, he only wants to use her, but eventually comes to believe she could achieve something significant. The film makes it clear that any exploration of her sexuality won't be accepted, and when Rosie moves on, she quickly finds herself engaged to and married to Jim. A career under the guidance of the mysterious Don King (Chad Coleman) appears possible, bringing commitment, hard work, and money—but as she gains success, it becomes apparent that there are serious problems in her personal life, cocaine enters the picture, and her marriage with her husband grows increasingly restrictive. Professionally, a major fight against Laila Ali looms, and personally, one has to wonder how much longer this damaging marriage can endure. The story of this woman's accomplishments is undoubtedly worthwhile, and I remember the excitement surrounding the Ali fight in 2003; however, despite Sweeney’s performance, I found it to be a film with an inconsistent rhythm and, honestly, rather lifeless portrayal of Martin’s life. It dwells too much on the early stages, glosses over aspects that would make her relatable, and frequently descends into a disappointing melodrama that takes away from the energy this should have had. Foster looks appropriate, but his character also feels underdeveloped; I really couldn't understand why she would ever be attracted to him, let alone marry him—particularly when he gave her a pink kit. For a film about addiction in its various forms, there’s no sense of urgency or excitement – I even glanced at my watch on occasion as the 2¼-hour movie progressed. The fight scenes that are included are well done, but there aren't enough to truly draw us into the complicated and intense reality of this woman's life; in many ways it felt like a mismatch, similar to some of her early bouts. It’s unfortunate.
