That doesn’t mean celebrities always like the ones that are meant as a compliment, but you can tell as audience members what the person is trying to get across.
I always enjoyed Cheri Oteri’s Barbara Walters impression because it seems to come from a place of love.
Sometimes that’s having a good-natured laugh at someone’s expense and sometimes that’s giving a middle finger.
That’s really the dividing line between a lot of impressions.
