Do you enjoy him before or after his wife died? The way he is afterwards is pretty dark, but I love how straight-edged his comedy becomes. If anything, I imagine that's probably how Mark Twain was on stage. I would give my unborn child to time travel to one of his talks. We can talk about the films when I get my comic back!I'd love to see the end result : )
I'm not sure in what phase of his life he was when his comedy became more political and like you say darker. When he stopped with fluffy superficial comedy and went deep and to the core of the ugly of society. That's the part of his work that I really admire. His brutal honesty, even if he's insulting you, you still love him for pointing out the absurd and rotten in society.
Good to know you liked them : ) There are a few other documentaries on the subject under the Universe category of Lucid Tree if you're interested.
