The story unfolds through flashbacks, presenting an older Baroness Thatcher, portrayed by Meryl Streep, grappling with the loss of her husband, Sir Denis (Jim Broadbent), and experiencing dementia that troubles her daughter Carol (Olivia Colman). This condition causes memory lapses—forgetting recent events while retaining clear recollections of pivotal moments shaping her decade-long reign in British politics. While Streep successfully captures Thatcher's mannerisms and tone, the film’s shifting timelines diminish its impact. It becomes difficult to find fault with the woman or her methods when she is primarily shown as the diminished figure she became later in life. A sense of sympathy arises, likely for everyone involved, and it seems no one desired that outcome. The narrative's brevity doesn't adequately represent her career—the significant triumphs and setbacks, her international standing, even her eventual decline—resulting in a superficial portrayal of this divisive figure. Seeing Streep’s skill is reason enough to view the film, but as an examination of Margaret Thatcher or her political legacy, it proves underwhelming.
