I'm going to look up Frimet Goldberger...I don't think I've come across anything from her on this.
As for the criticism, I'm skeptical of it in this case for 2 related reasons. The first is that the Hasidic community, or certain sects therein, have been known to attack anything critical of them in ways that aren't exactly truthful, I've seen this a few times in unrelated cases, so "the Hasids said..." doesn't hold a lot of weight with me in the she said/they said argument. Secondly, as soon as someone uses something that doesn't actually exist as an attack, I lose faith in their argument. In this case, it was claim that Feldman was forced into a marriage when, in fact, that is not what she wrote in the book. She was happy to get married and never resisted it. However, I will be interested to see what Goldberger writes--I admit that I give more credence to someone who is willing to put their name to it.
I did, in fact, just finish reading Unorthodox and I was actually underwhelmed by it. It wasn't so much the differences between the book and the Netflix show (which are many--I wouldn't even say that the show was based on the book), but rather that Feldman fell into an all too common memoir trap where the memoirist is very convinced of their own perfect and superiority. Feldman makes no bones about the fact that she believes she is the smartest and most beautiful of them all and only she could accomplish being a woman to leave the Satmar community. It just became annoying, which is too bad because there was much in that book I found interesting.
My next book is Rodham, which should be interesting....
