Amazing Anna Gunn
This very talented actress struck the right tone in almost every scene of her complex character. From the loving,caring wife and devoted mother, to the pain and horror of realizing what her husband had become, to the courage to stand up to the moral monstrosity of her husband and try to salvage her family and moral compass by helping her sister and wrongfully damaged brother-in-law with their medical bills.
There are so many horrific, amoral characters on Breaking Bad that Skyler distances herself from them by trying to keep her moral anchor in an ocean of greed, brutality, endless violence, and complete moral breakdown, which is our current culture.
