The reviews split almost evenly, and the one thing nearly all agree on is Sydney Sweeney. Critics praise her physical transformation and her committed, unglamorous playing of Christy Martin, and several say the boxing scenes are where the film is at its best. Merritt Wever, as Christy’s judgmental mother, and Ben Foster, as her controlling husband, draw steady praise too.
The argument is over the film around her. The positive notices call it moving and rousing, a sports story that swerves the usual formula. The sceptics find it bland, formulaic and overlong, with a montage-led approach that keeps Christy’s inner life at arm’s length and a dour tone that never lifts. Two British outliers go further: Sight and Sound and The i Paper argue that Sweeney herself falls short, either dulled by the script or unable to catch Martin’s complexity. Few others agree with them.
