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 instant, it’s a cycle of diminishing relapses and rebounds.
