The things I liked most about the film were the robots boxers. Some of the scenes are memorable because they're very strong, but the style and plot are very complex.
The story starts in 2020, human boxers have been replaced by robot boxers. Charlie Kenton (Hugh Jackman) is a former boxer who owns a robot, Ambush, competing in unsanctioned matches and exhibitions whit it. At a rural fair, Ambush is destroyed by Back Thunder, a bull belonging to prometer Ricky (Kevin Durand). Having made a bet that Ambush would win, Charlie now owes Ricki $20,000 , which he doesn't pay before leaving.
