Loved it! Maybe a bit too long to my taste (lots of denial!), but I like that for once we get to see their budding (and oh so serious already) couple a little longer before the credits. My only complaints would be that Syd uses far too many ableist slurs ("you're nuts", thrown about 30 times— it's insensitive and it gets really old) and that everyone's far too perfect. Smart, gorgeous, rich, perfect women living perfect lives, with (lots of) great wine, great cooking and great classical music tastes. Oh, the jealousy.
Also this book could use the B word sometimes. I know about compulsory heterosexuality but it doesn't always explain why "I'm gay" is the go-to explanation of someone falling for a woman after four (even shitty) years of marriage with a dude.
