From NetFlix:

Meryl Streep provides a subtle and nuanced portrait of Margaret Thatcher, the first female prime minister of Britain, whose political career and determination changed the rules that had limited women’s opportunities for leadership.

Sometimes I criticize Meryl Streep for some annoying and often used facial smirks. However, in this film she is the best I have seen. If nothing else she portrays the sadness of aging and the accompanying changes in personality, memory, and looks. My own mother (who died at the age of 97 on March 1, 2012) went through the same changes during the last 5 years of her life. Streep gets it right. And speaking of “looks”, whoever did Streep’s makeup did a remarkable job. No matter the age portrayed, you knew it was the same person and the makeup artist had captured that stage in Thatcher’s life perfectly.

It would be helpful to hear from a Brit who had seen this film in order to know how well Streep captured Thatcher’s manner of speaking.

Do not be put off by the main theme of Thatcher’s late life decline. You get to learn the history of her career from political neophyte to her success as prime minister. There are actual film clips that show some horrible violence during the riots as well some ugly Falkland Islands war clips. If the film is accurate, it was sad to see her career end owing to an arrogant hubris (sound familiar?).

Most touching of all was her relationship with her beloved husband Denis Thatcher (played by the wonderful Jim Broadbent).

Many British actors appear in the film (Iain Glen, Nicholas Farrell, Anthony Head) , most of whom are familiar from British TV.

Ignore any naysaying critics. This film is well worth seeing.
