Worth it just for Into the Woods & Assassins. I didn't read the whole thing, I haven't seen Passions and skipped most of the movie section except for Dick Tracy. In some ways this volume feels lighter, but since Sunday, Woods, and Assassins are my favorite Sondheim shows I still liked it more.
Interestingly I felt like he was harder on his work in Volume 1. Maybe it's just that he got better as he got older? Or is it that the shows aren't as old?
I've always had extremely mixed feelings about Act II of Sunday In the Park With George and I was hoping he would dig into that a bit, but I guess he feels like it's not dated and tacked-on, so OK! Just me.
