I am a first time watcher and I am surprised at how much I like the series. The one thing that won me over was how every episode felt like a lesson in history without feeling like a lesson.
I like Gillian Anderson as Thatcher. I think she did a good job (Anderson, not Thatcher). However, what put me off was that in the show Thatcher started her tenure as prime minister as an old woman.
In reality she was in her 50s when she moved into Downing Street and although that was a bit older than it is today it wasn't as she was in her 70s.
But that's how she looks like, talks like and walks like. And when she leaves Downing street 12 years later she is exactly the same age. Not a day older.
Did anyone else notice that too?
