 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 .
