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. " Hadadi particularly criticized the series for its inconsistent and shallow characterization of its protagonist, Grace Fraser, compared to Kidman's Big Little Lies character, Celeste Wright: "In prioritizing unbelievable twists rather than steady character development, Kelley re-creates Grace as a shell of Celeste, making her the hollow center of The Undoing. Grace wears the same kind of clothes as Celeste, and has access to the same powerful allies as Celeste, and lives in the same sort of mansions as Celeste. 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. " Eve Gerber of The Atlantic criticized the series for glamorizing domestic violence, noting that critical discussion about the series largely avoided the subject and instead focused more on the series' production values, makeup and costuming.
