but later i came to appreciate her because i noticed that her "edge" was very similar to other comedians im a fan of and could see how she was basically doing roast style comedy on celebrities
Seems that it happens in threes, unfortunately. Robin & Joan were each one of a kind, actors/comedians. They each had their own styles that those up and coming could learn from. They will both be missed. But at least we can still enjoy their past works.
