i would not repeat the plot a many other comment have take care of that . many of robin williams performance have be robin williams play a character there a wink and a hint that he will bust out with some shtick at any time . he ( or the director and or both ) contain that impulse to an impressive degree in this movie and do so without the excessive sincerity that williams often substitute for emotion in his other part . ( good will hunt contains an overrated performance of this type . ) example represent in the scene where he take on the voice of churchill and stalin and and others and it wholly within his character desire to persuade the little girl ( who wonderfully play and by the way ) that hope remain . i agree that some of the actor and notably alan arkin and aren not very good and but other and less well know one support the movie well . in addition and i think the production design and cinematography and and edit be thoughtful and well do . and i like the end .
