I think I should have just read a biography of either or both of these women, because they led extremely interesting lives which the book managed to make fairly dull. I wanted way more about actually making movies, and less angsting about boys, and a lot of the writing felt overwrought and melodramatic. It kept skipping over actually making the movies and what that was like into other issues.
The author backed herself into this weird smarm corner of saying the main character was completely fine with gay people, and then immediately insisting that she didn't get lesbians at all because who doesn't like cock, amirite? By the way, the character really likes cock, and isn't gay at all. Look, I don't mind stories about two women having a friendship rather than a romance, but the notgaynotgaynotgay(but not homophobic!) dance got old a long time ago. I felt like I'd fallen into Xena gen fic from the '90s. At the same time, the author had the same characters not blinking at the racism in the industry in general and Birth of a Nation in particular. So I'm not sure why period-typical racism was okay, but period-typical homophobia was not?
I did like some of the discussion about being a woman in a male-dominated field, which mostly managed to stick to period language and not sounding like it was cut from modern day. But so much of it was telling not showing, as we very rarely see the dynamics on set, or the sets at all, just hear about them after the fact. I looked at some reviews to see if it picked up, but apparently the middle is even more draggy and about boys, so I bailed.
