Here's the thing about Kate Mulgrew. She was born for this role, even more than she was born for her role in Mercy. In Mercy she's the mother figure to her husband and at least one idiot son but fails big time with the daughter. She's hilarious.
THE WHOLE SERIES SHOULD HAVE BEEN ABOUT JEANNIE FLANAGAN.
But. In Orange she is the mother figure to EVERYONE. She's dry, she's vulnerable, she touches, she cares, she has insight, she stretches herself, she has plans unseen by and for those she motherhens, she's fallible, she's vulnerable, she's idealistic despite being in prison, and she's tough as nails.
Kate Mulgrew does all of this like breathing. She can tell you any of these stories with a look, a sigh, wave of her (VERY SEXY) hand. This role is perfect for Kate Mulgrew, PERFECT.
