This is one of those great autobiographical performanes. Meryl Streep is great as Margaret Thatcher. However, there isn't much more substance besides that. At least there wasn't for me. Maybe history buffs would be much more in to it. What I watched was a prominent historical figure going over the events of her life while trying to come to grips with her husband no longer being alive.
I would lukewarmly recommend this movie to people solely for Meryl Streep's performance. Outside of that, the movie is just kind of there.
