It’s extraordinary that anyone as funny as Robin Williams can also create the impression of being so nice.… Mr. Williams doesn’t need sex, malice or self-deprecation to round out his repertory. He doesn’t even need real experience, or even real jokes. Mr. Williams simply assumes the manner of a small boy impersonating a stern, grown-up hero and whizzes from one crazy proposition to the next with cheerful aplomb. When the crowd responds appreciatively … he seems to beam with sweet, uncomplicated pride.
