I agree with Mikey, I though it was a brilliant drama.
One of those programs where I say "I wish I had written that".
I loved the structure of it (which seems to have confused a lot of people) with the "older" Barbara watching her life go by in a sort of flashback.
Some scenes were very moving (I wont give any spoliers away) but it would certainly surprise many people that Barbara was nominated for both a Bafta in the UK for her theatre work and a Tony for her theatre work in the USA.
Don't go by all the negative comments, watch it and make your own mind up.
