Best show I've watched in quite some time. If you enjoyed Big Little Lies, you'll likely enjoy this too. The Undoing definitely keeps you guessing. Although many of us have been spoiled by full-season releases on streaming services, waiting a week for the next episode helped build suspense and allowed time to discuss theories with friends during covid lol. It's comical that many of these "bad" reviews seem to focus primarily on changes to Nicole Kidman's face (??) or claim to have disliked it but go on to spend even more of their precious time writing an essay-length review. I think some of these are either fake or written by people who should just relax and enjoy it for what it is - a purely fictional tv show for entertainment purposes. Perhaps those who need everything to be "realistic" should stick to factual biographies &/or dry documentaries.
