It's a really well-made show. While not every episode is about marginalized groups, when they DO tackle them they do them in ways that are respectful, thoughtful, and honest. They call out the problems in culture that lead to bad things like murders happening, and their getting brushed aside that lead them to never being solved. And every episode nails the feel of the period so well, is beautifully written, and contain really compelling humanity that affects me like few TV shows ever have.

But seriously. Start with that ep I linked to, "Best Friends." PHENOMENAL.
