"American actress Jaime Presley from North Carolina" is one of my more successful characters, all I had to do was a Southern American accent and people think I'm a completely different person.

Then again, nobody ever expects an actress to be playing the role of another actress.

That show was a masterpiece that literally nobody talks about. They did the impossible of making a flawed cast that wasn't just full of awful people who the writers desperately try to make you like (often through justifying extremely problematically) Their flaws are a key part of their characters, but don't define them as a character. It also allows them to organically go back on continuity shifts, because in the real world change isn't either instant or not at all, it's a cycle of diminishing relapses and rebounds. The ups and downs make for great content.
