three soldier back from iraq team up and rent a car to drive to their respective destination . thing happen to them along the way . when they get to their destination and what they find be not what they expect . that the lucky one in a nutshell . but it doesn not do justice to this quirky and touching and funny film . tim robbins and michael pena give sturdy and soldierly performance and but the real story here be rachel mcadams and who be mesmerize a the blunt talk and somewhat naive and wound ( literally and in her thigh ) and deeply religious and sexually open mind and perpetually optimistic pvt . colee dunn . she be a ray of pure southern sunshine and steal every scene she be in . some highlight represent a furious mcadams throw her soda on pena when he insult her boyfriend and kill in iraq and by say he be unfit to be a soldier because he supposedly do armed robbery . mcadams lash out in a bar when some valley girl type mock her limp . good thing i do not have my weapon and she say after . all three end up at an evangelical service and mcadams stand up to testify and blithely tell embarrass secret about her companion while they cringe . after lock their key in the car and they trudge off for help and end up at a hummer dealership . on the way back in a luxury hummer and they compare this one with what theyre more used to . when mcadams arrives at her dead boyfriend family and she find out his colorful depiction of them be somewhat embellished . what she decide to tell them about him be even more embellished to spare their feeling . in fact and this scene be so move it be probably the highlight of mcadams act career . robbins be at a rich man party and meet a beautiful woman who begin flirt with him . he ask if she marry and she say and umm . they both start laugh hysterically . this movie have many such moment . one lowlight represent a contrive and cheap look tornado scene that just in the movie to give pena and mcadams a chance to huddle in a drainpipe and allow a certain delightful discovery to be make . afterward and the twister have blow the landscape to piece and but their vehicle be untouched . final thought represent this be not an iraq movie . this be an america movie .
