I read some of the reviews after watching the first episode, which I liked (although not as much as the original series), and I found myself laughing so hard that... well let's just say I was drinking a beverage at the time.
People are complaining that the show, set in 1938 Los Angeles, is misrepresenting white people of the time as propaganda. In one review, it critiques the representation of segregated neighborhoods (as if the Civil Rights Movement had already happened? Or maybe they think it was never needed to address segregation issues? I'm not sure.). Also, keep in mind that only a few years later Japanese Americans were interned unconstitutionally (Korematsu was later reversed with the Court admitting it was one of the most biased and offensive decisions in history). It really shouldn't be hard to imagine that race relations were as they are being depicted.
At the time, white people were largely the bad guys by today's standards. This isn't to say, however, that being white meant a person was bad. Really, white people at the time just had more resources and power, so it was easier to be the bad guys. Indeed, this show includes a scene where a Latino character, upon gaining some power, immediately uses it to kill white people without any feeling of humanity or remorse. The takeaway isn't that only white people were prejudiced: it's that racial prejudice was commonplace across races, but white people had most of the power (e.g., police force, political clout, judges, money).
What this should really make us think about is whether we will be seen as the bad guys one day, and for what reasons. Will we be remembered well for protesting to end quarantine so people can have entertainment and haircuts? Will we be remembered well for not following the wisdom of the Bible and turning away the refugee among us? Will we be remembered well for mass incarceration of largely black men for non-violent crimes?
It's really hard to say, but studying constitutional law cases recently, I can say that the setting this show describes is, if anything, too kind in how it represents the ubiquitous racism of the time.
