Smith has to deal with both public and personal issues, which sometimes overlap. She has children who don't understand why her job has to take precedence over their needs. And she has assistants who don't always have her best interests at heart.
Things are never black-and-white in her world, and Smith is seldom foolish enough to think they are (although she has her moments). Surprisingly, her integrity is an asset, rather than a handicap--but not in a schmaltzy way. She succeeds, not because she's more ethical than her male counterparts, but because she's ethical *and* smart *and* tough-minded.
But I emphasize that things are not clear cut and even when Smith is right, she can also be wrong.
One of the pleasures in this series is the presence of Denis Lawson, who plays her political attaché. Although he is her loyal ally, he often has his own agenda.
All in all, a very thoughtful and intriguing drama.
