I'm really in love how they let Janeway become harsh. It in the first few season she is soft, playing romance holonovels, touched by the tragedy of the vidian phage, etc. She has so much empathy for the people around her, bursting with love for her crew. That loves still there, but she's also adapted to the harsh enviroment of the delta quadrant. Cunning and ruthlessness are her new modus operandi. Her heart can only hold her back so much...
I love her moral greyness. I love that she is bent on bringing Ransom to justice, by any means necessary. I love how the crew opposes her almost lethal need for revenge. Desperate to have all the protocols and regulations to mean something. They have kept her strong so long.
I love you Kathryn Janeway, for all you're complexity
