This episode simply took my breath away.
I was apprehensive about HBC at Princess Margaret. I love HBC, but I just couldn't quite see it, but now I'm convinced. I think that, as an actress, she's identified by her "stranger" roles, although she really seems to shine in more "normal" roles (you know, ones not in Harry Potter or Tim Burton movies). I do hope she gets the recognition she deserves for this role.
I never expected an episode of this show to make my double over with laughter, but the entire sequence that cut between Wilson and the Queen and Margaret and LBJ did just that. This LBJ may not have been nuanced but it was a home run after seeing the Kennedy's last season.
What really got me was how well the complex relationship between the two sisters. And none of that was scripted, it was all acting. I think the show hit the home run with Olivia Coleman and HBC.
