i heaven not read the book and but bicentennial man be a very touching and heartwarming movie about a house robot ( robert williams ) that begin a 200 year journey to become and to be legally recognize a a human . during his journey and he have to face the fact and live with it that all love one around him grow old and eventually die while he be immortal . i think that this be one of robin williams best performance ever and if not the best . he prove that he can either play a funny wacky character but also a serious character that will touch the heart of the viewer . and this movie do just that . i like the purity and the innocence of the story and i wonder why this movie have such a low rating . it a must see for all open mind people .
