Somehow, Chaplin fully embodies his twin comic personae, deals with the issues of his own time, but looks at the audience with what could be 21st-century eyes. The last couple of seconds are splendidly defiant and uningratiating.
Although I prefer late Chaplin to early Chaplin - "The Idle Class" is hilarious. Chaplin's light-hearted barbs at the rich are always appreciated. prefer his darker, more savage critiques of Capitalism ("Monsieur Verdoux," etc) but - hey, It's Chaplin. What more needs to be said? He had more talent in his foot than most "actors" or "directors" have in their entire bodies. Even when he's bad he's great.
