★★★ (out of ★★★★)  

It isn't long into Netflix's sports biopic Nyad when we realize record breaking long-distance swimmer Diana Nyad has that same competitive itch most world class athletes can't seem to scratch, even long after retirement. Many are initially plagued by second thoughts for walking away, realizing later time will always catch up. In that respect, Diana's urge to return at age 64 to finish what she couldn't decades earlier isn't surprising. But the impossibility of her goal is, regardless of age, gender or physical conditioning. She can complete this grueling 110 mile swim from Cuba to Florida because failure isn't an option, even as her stubbornness and oversized ego frustrate those helping make it happen.

The burden Diana carries to be the best is heavy, and as pieces of her troubled past are shown in fleeting glimpses, that desire starts making more sense. Attempting this swim still seems crazy, but we get it, and much of why rests on Annette Bening's performance in the title role, which is defined by her willingness to explore unlikable places with Diana's prickly personality. Bening specializes in steely, determined parts, but the sports psychology angle here really distinguishes it, as does her pairing with fellow acting icon Jodie Foster, who's arguably even better in a welcome, exciting departure.

Shortly after her 60th birthday, former marathon swimmer and ABC "Wide World of Sports" correspondent  Diana Nyad (Bening) shocks longtime best friend Bonnie Stoll (Foster) by announcing plans to begin training for the brutal Cuba-Florida swim she failed to finish in the late 70's. With the assistance of a steel shark cage, she veered off course, eventually taken out of the water after nearly 42 hours. A reluctant Bonnie agrees to coach Diana, but it's soon clear this is as much a battle against nature's uncontrollable elements as it is a test of the latter's drive and limitations. 

Looking to avoid previous pitfalls, Bonnie recruits grizzled navigational expert John Bartlett (Rhys Ifans) and an entire team of divers and scientific experts given the thankless task of providing the defiant Diana guidance she doesn't want or listen to. Unsurprisingly, this isn't a feat she'll be able to accomplish her first try, or maybe any of them, but for her there's no quitting until reaching the Florida shore.

As someone who sucks up all the air in the room, Diana has to humble herself enough to let the people around her actually do their jobs. In that sense, five attempts at this seems about right, even if few athletes would have the endurance to withstand one. Compellingly, the notion is presented that Diana could be more mentally equipped to do this now than in her physical prime due to experience and motivation that only comes with age. Of course, this sounds great until you're in the water and all the damaging effects begin to take hold.

On top of unmanageable tides, volatile weather patterns, sharks and deadly box jellyfish, Diana must contend with physical challenges and hallucinations her famished, dehydrated mind conjures up. With a collection of familiar 60's music comprising the playlist in her head and clad in a custom silicon face mask and suit, she's flanked by numerous boats and a professional medic. The nighttime scenes are most effective, creating a sense of isolating terror despite the fact she's hardly alone out there. It isn't lost on anyone she could die at any moment, her odds only worsening with each subsequent try. During this, flashbacks of a traumatic childhood event are cut in, informing the woman she'd later become.

Dina's penchant for exaggerating her already impressive accomplishments is a flaw Foster's Bonnie pushes back against, calling out the swimmer's self-centeredness and aversion to the truth. Aside from that, Julia Cox's screenplay is mostly reverent in its depiction, as Bening and Foster naturally play off each other, conveying the rhythms of lifelong friends incapable of sugarcoating anything. Whatever Diana dishes out, Bonnie gives right back, with Foster doing great work as a warm but no-nonsense voice of reason. Rhys Ifans also impresses as an exasperated navigator more than willing to put Diana in her place when necessary.     

Uplifting as it is, Nyad isn't a game-changer, but goes down easily under the skilled direction of Oscar-winning Free Solo helmers Elizabeth Chai Vasarhelyi and Jimmy Chin. But unlike that documentary, this narrative feature about going to extremes will probably play better for those unaware of the end result and ensuing controversy. That the 2013 swim is noticeably absent from the record books is a detail the film doesn't touch for obvious reasons, instead showing real footage of Diana's media appearances over the closing credits. But even as all the attempts at completing this achievement sometimes keeps the action stuck in repetitive mode, it succeeds by emphasizing the failure and tireless work that led her there.
