I liked the Undoing a lot but Tell Me Your Secrets is so dark and depressing and slow and there are no redeeming characters except the ones who are killed.
Unfortunately, I find I'm watching til the end to find out what happens and who did what.
It's like those series that you can't stop watching but can't wait til its over so it can be over and you can watch something good.
