sandra bullock paint a believable picture a the troubled detective and though see her a a cynical man eat victim turn persecutor require a leap of faith ( or two ) . the two creepy troubled kid be portray adequately by ryan gosling and michael pitt . i do have quite a bit of trouble get ben chaplin into the equation ( same problem arise when watch the truth about cat and dog ( http represent or or u . imdb . com or title or tt0117979 or ) . i mean and when you put an englishman into an all american movie and shouldn not there at least be a reason to put him there . shouldn not there be some story lead up to the fact that an englishman be serve a a detective on an american police force . shouldn not there be some dialog point out and explain that rather obvious fact . or even some joke about him be that english . he look out of place here and a he look out of place in the truth about cat and dog . producer really should take notice and it distract and annoy the audience ( at least me ) . nothing wrong with chaplin acting and it just a matter of make an actor who be out of place believable and not put him somewhere without a good reason or a storyline . the movie itself represent well and thriller and especially those deal with solve a complicate crime and require some suspension of disbelief . this one no different while actually and it require quite a bit more effort than usual . in order to make bullock smart enough to crack the case despite of all the pressure require her to let go of it and some unrealistic assumption be be make about the evidence and and i be sure a lot of people who watch it have a few moment of come on and this be highly unlikely under the circumstance or even hey and you can not brush evidence aside like that to wrap this movie up . like i say represent reasonably entertain and watchable . just do not use this a required viewing for detective exam . there be no shortcut there .
