Her greatest critic was Kenneth Tynan who ridiculed Leigh's performance opposite Olivier in the 1955 production of "Titus Andronicus", commenting that she "receives the news that she is about to be ravished on her husband's corpse with little more than the mild annoyance of one who would have preferred foam rubber." He was also critical of her reinterpretation of Lady Macbeth in 1955, saying that her performance was insubstantial and lacked the necessary fury demanded of the role. After her death, however, Tynan revised his opinion, describing his earlier criticism as "one of the worst errors of judgment" he had ever made. He came to believe that Leigh's interpretation, in which Lady Macbeth uses her sexual allure to keep Macbeth enthralled, "made more sense ... than the usual battle-axe" portrayal of the character. In a survey of theatre critics conducted shortly after Leigh's death, several named her performance as Lady Macbeth as one of her greatest achievements in theatre.
