Charlie Chaplin was a funny guy 100 years ago. He made a few really good silent films, almost all of them dependent on the Little Tramp character. Viewed today they are still funny, though perhaps a bit cruel. I'm not sure he was any funnier than his contemporaries, and Buster Keaton still gives me just as many laughs without the cruelty.
Chaplin failed miserably to make the transition to the talkies, as did many others Laurel and Hardy are the best comedians to make the change, and I think their best work was later in life.
Why the adoration? I don't get it. And why a focus on his Limelight which was surely one of his weakest films.
