As a death positive anthropologist, I was looking forward to reading this book, as it would be a great insight on death culture around the world. I enjoy Caitlin Doughty's personality and profession on both her YouTube channel and in her books, and while she very good at describing the cultural things she has seen and learned, she does so from a more personal viewpoint, than an academic one.
I don't blame her for this, she's a mortician, not a cultural anthropologist after all. That expectation was on me, my bad...

She's very respectful towards the living and the dead in her book, but as a non-American reader, there was one cringe-worthy comment she kept making throughout the book, which is a commentary made by many people whom have English as a first/only language; the constant surprise of the near perfect English spoken by those, who have English as a second, third or fourteenth language.
There is a charm and social identity to be had, when it comes to accents and dialects, and most humans will giggle at foreigners mispronouncing words which we ourselves consider simple, that's just a fact of social interaction.
So my one critique, which is not at Doughty herself, but the culture she lives in, is that commenting on nearly perfect English is like commenting on nearly perfect handwriting, nearly perfect math or nearly perfect cooking...
Please stop being impressed at other peoples ability to go to school...
