The writers need to do a little bit more research about the era. Without spoiling too much, the writers add diversity, but it doesn't work well at times because the writers fail to go in depth about the racism and homophobia of the era. I personally don't mind adding black or other minorities to shows. I'm a black woman myself. But why include black people in unrealistic roles in a show set in the 1940s? It's not representation. It's a complete lie and undermines the plight of black people and other minorities during that era. I saw this in Ryan Murphy's Hollywood as well. Again, sugar coating racism and homophobia. To be LGBTQ and/or a person of color was DANGEROUS back then. The stakes aren't realistically high enough in this show. If you watch the show, some parts are pretty tone deaf to the racist policies that occurred in the 40s.
Despite this, the show is okay. It's not great. I've never seen AHS so I don't have that frame of reference. The acting is very good. If you have time to waste, watch it. It's not unbearable although. Although the historical accuracy is trash.
