I adored Kira right from the very first moment she appeared. It was like someone had taken Ro from TNG and upped the badassery by a factor of about a hundred. The initial (understandable) anger soon gave way to a more mature but no less powerful character, who to me has always been the central character of the series. Nana gave that role everything she had, and she's easily the best female perfomer the Star Trek franchise ever had. She's so underrated it isn't fair.
One of the things that I love about her performance is that she is so into being a part of the world of DS9. Every moment she's on screen Kira is constantly reacting to what's going on around; looking, thinking, responding. Even if it's a 10-second cameo in a Klingon episode she is in the moment more than probably anyone else around her. She's like that in every show or film I've ever seen her in, actually. If I were an actor, she is the kind of actor I would want to be like.
That dedication to the part also comes across in interviews she does, even today; Kira isn't just a role from 20 years ago to Nana, she's more like a real person with a life of her own somewhere. That is so cool. As are the stories that she would spend time on the set staring out the Promenade window at the stars, or that she would get overexcited at the thought of commanding the Defiant or getting a promotion. Just like any of us here would if we were in that situation. She thinks this show is great for exactly the same reasons we all do. She gets it. That is
wonderful.
It's also worth mentioning (although I've probably worked this into every post I've ever made here) that Nana is an unbelievably lovely person in real life. I've met her at...ooh, 5 conventions since 2007 and cannot say enough good things about her. Incredibly friendly, very warm and always happy to talk to anybody. A truly remarkable woman. Meeting her was one of the greatest and most important experiences of my life, so if you ever get the chance to see her
go do it. You won't regret it, she's the best.
