As someone who read the book I have to say it honestly didn't leave me with a better impression of men at all. It kind of did the opposite.
There were scenes where the men were cheating on their wives with strippers and one guy basically says that men have their needs and women can't understand, it was treated like some profound thing.
Another scene is when she acts as a salesman, the only saleswoman they have is given the hardest job in an effort to make her quit. This is acknowledged as "just as how it is"
The passages about the strip clubs are the most depressing depictions of strip clubs I've ever read frankly,and paint men in an extremely disgusting light.
She also flashes one of her friends when she reveals she's a woman. Even though he clearly didn't want to see that.
There was a section where men were supposed to vent their anger in some of kind of men's support group and a lot of them wrote about killing their wives, it was brushed off as "guy"thing. You know about how all men have violent anger in them and how their relationship with their wives is like their relationship with their mothers etc.
I know I'm simplifying but frankly sympathy was the last thing I felt reading a lot of those passages about women.
Were there good parts? Yeah. I also already knew most of this suff about men's struggles before I started it so there was nothing mind blowing.
Honestly it felt like she found the most stereotypical (more or less) guys she can find becuase that's what a real man is to her. There wasn't a lot of variety. And yes that's even after reading the chapter on monks.
Also she just had a really bad view of men. Like she kept acting surprised when men were anything but complete pieces of shit. She had some really negative beliefs about them.
She went to a lot of trouble and had to check into a psychiatric hospital afterwards
She already had mental health issues going in, and she talked a lot about her guilt about pretending to be a man, especially when she was listening in on intimate things men were sharing. Ofcourse I'm sure the loneliness of living as a man also affected her.
There are other books like The will to change and of Boys and men. Although I haven't read them yet but I've heard much better things about them to be honest.
