i have see many dustin hoffman movie like straw dog or rain man and i like them and but his character be much to often calm or even shy person . i expect him to be in this movie the same a he be in straw dog and but i saw a totally different person . he be much more energetic in this film and kinda remind me of al pacino in serpico . the movie be very interesting from begin to the end . i like the way dustin hoffman character be ready to do just about everything to stay with his son . this movie be also reveal . personally and i think it show that people should learn to find a compromise them self without involve other people into issue .
