The Italian Teacher

This book was not a good match for me. I hope others love it. I found to be as dull as watching paint dry.
At first I was worried I wouldn't like it because I know so little about the art world. Really, The Italian Teacher is about a famous patriarch, who is a major jerk and a terrible family man. It is also about the life of his son, Pinch. I physically hurt me to watch Pinch get hurt over and over again and then come back, begging for more. His preoccupation with his father and his father's opinion of him leads him to have a sort of non-life. Really, what happens to Pinch as an adult is just as frustrating as his childhood but now Pinch is the abuser-of himself.
My reading notes on this book repeat the same phrase multiple times: is this ever going to end?
How can I still have 200 pages left? UHHHHHHGGGGGHHH.
I stuck it out and finished it because I'm trying to read the entire shortlist of the 2019 TOB, but I would have DNF'd this a few chapters in otherwise.
It's just not my cup of tea, obviously.
