firstly and i have not read asimov book and therefore can not remark on any error in translation from book to film . i have read many of the comment post here on the imdb and but fail to see why so many people feel the need to mention that the world be perceive a perfect in the the future and maybe it be and maybe it isn not and the fact be and it not important . this movie quite simply follow the life of a man trap in a robot body and his quest to be accept in the world and and be allow to love and cherish the people close to him . i have to say that i do not expect much from this movie and i think it would be a kid film and full of typical robin williams style laugh and i be way off in my assumption . this be probably robin williams best performance and it be a very emotional journey through change and development of the human condition . overall the film be quite amusing and very touching and be full of realistic character all very well cast to not overshadow andrew a he quest over 200 year for acceptance . a great movie positive .
