So I'm not overly happy with how the series looks, but the book was a great homage to and critique of Lovecraft. It's not really revisionist history anymore than any other fiction. Basically, it takes the reality that Lovecraft was great at evoking feelings of existential helplessness but also REALLY hated basically every minority and decided to marry the two ideas rather than separating them like a lot of people want to do. One of the obvious issues with Lovecraft for readers from marginalized groups is that the loss over power and meaning aren't that scary because they never had power, and they'd already been told for years that their lives didn't have meaning. So reading Lovecraft through a black lens means you don't have to focus on obscure unintelligible forces. Some exist in the book, but they don't really matter. What matters are the people in power and how insignificant the main characters are to them, and how the MCs still try to find meaning in their lives anyway.
It's a really good exploration of racism from the 30s and earlier, and there are a lot of emotional points while also sticking to a brisk pace due to the book being structured as a series of short stories. I have a bad feeling that the series is going to crank up the supernatural, thus defeating the purpose of the book. It'd recommend the book highly unless hearing about racism triggers you (which I'm guessing it does looking at your post). It's about the black experience at the beginning of the last century. Like it or not, there was a ton of overt and senseless racism then. You simply can't leave it out.
