My Talmud study group had high hopes for this book and were disappointed, but we probably know more about Talmud than most non-scholars. There is a dearth of books about Talmud for folks like us in the middle territory -- we know a lot but aren't academics -- which frustrates me, but of course it's also true that we're a pretty niche audience. This is Rubenstein's one "popular" book, and a lot of it read like transcripts of jocular undergrad lectures.
Rubenstein is good when he's doing historical readings of these tales, although in some cases we wanted a lot more such history. And I appreciated his literary analysis of the tales, which is his area of academic expertise; I didn't always agree with his reading, but I always found them interesting. Where the book was not great was when he was doing modern connections to the Talmud tales, which felt like a weak attempt to say, "see, this is actually relevant!"
