There is no way I would even want to watch this, I try most of the time to pretend she never existed despite now living in a country she dreamed about. However, if it does in fact focus on this, it reminds me of when Spitting Image used to make fun of the Alzheimer's-ridden Ronnie Reagan while he was still alive. I had no time for him either but I felt deeply uncomfortable at that.
I think though that a much better film will be made when the thirty year information disclosure block expires. Oh yes, THAT will be a much more interesting film about the evil stain on our history.
Still, Meryl Streep's (and Faith Brown's) imitation of the tyrant will always be better than Thatcher's imitation of a human being.
