When I read the criticisms in the press and blogs about the work, I found it telling that most of the criticism about Graeber and Wengrow's book is from non-experts. While experts seem to find it a breathe of fresh air.
I personally don't have enough training and education in anthropology and archeology to properly interpret the evidence. I suspect most readers here do not. That's why it's such an important work, because it synthesizes the latest research. Turns out a lot of it is counter to a lot of contemporary works that don't rely on such depth.
