I saw the documentary and it is very good. It's easy to see her as mean, but she was doing a brand of comedy that has mostly passed out of favor these days, Don Rickles et al were doing it at the time she came on the scene. It's incredible that a woman was able to break in to that kind of ballsy, mean-spirited form of humor and then that she reinvented herself so many times, kept herself relevant, kept the old jokes up to date and kept going decade after decade. I looked up a you tube video of the scene from the documentary where she deals with the heckler so well, and the comments were absolute poison, so anti-semitic, so angry. She didn't care about the abuse she got as long as she was making people laugh. She said stuff so mean, so crazy that you couldn't believe anyone would dare to say it.
