[3] The Undoing was the first HBO show to gain viewership every week over the course of the season, and was the biggest American series to launch on Sky in the United Kingdom, beating the record previously held by Game of Thrones.

The miniseries was written by David E. Kelley who also serves as executive producer alongside Nicole Kidman, Per Saari, and Bruna Papandrea.

[22] In March, Fala Chen, Édgar Ramírez, Lily Rabe, Ismael Cruz Córdova and Matilda De Angelis were added to the cast.

The website's critics consensus reads, "The Undoing is a beautifully shot mystery that benefits greatly from Nicole Kidman and Hugh Grant's performances—if only its story was as strong as its star power.

[32] Kristen Baldwin of Entertainment Weekly gave the series a 'B' grade and wrote, "Through all of the misdirects, the characters' dumb decisions, the dreamy detours, The Undoing kept me guessing—and, of course, gloating over everyone's misfortune.

"[34] Assessing the series as a whole following the finale, Roxana Hadadi of Vulture unfavorably compared The Undoing to David E. Kelley's previous series, Big Little Lies (also starring Kidman), stating, "Kelley re-created the elitism of Big Little Lies when adapting You Should Have Known into The Undoing, but neither its introspective spirit nor its curiosity about the inner lives of women."

But Kidman’s performance here is mostly one of wide, shocked eyes and blank, inexpressive despair; her Grace rarely, if ever, talks about herself, her emotions, or her decisions.
