Yea, we need people to relate to. Not only Dr. Cox, who's supposed to be kind of hateable, but Dr. Dorian as well are quite flawed. It's almost over the top a bit. I think some shows, (particularly that one) wouldn't be shows if they didn't speak so closely to the human experience. These characters are all walking around making silliness of our own insecurities, and... that's just funny to a lot of people.
