Kira is a strong and tough female character, who has lived a harsh life and developed a necessary armour to protect herself, but underneath she has great pain and kindness, as well as the capacity of forgiveness and understanding for some of those that occupied her world and oppressed her people. She is probably the best developed individual Trek has had, definitely the one who has shown progressive and consistent growth. She has more character and heart in her left pinky that in NuUhura's entire person.
Don't misunderstand me. I am not in any way comparing Kira to nuUhura. I only mentioned nuUhura because her name was mentioned previously in one of the posts above.
The biggest problem for me, is that writers typically write their version of "strong" female characters as "take no bullshit" from anyone, particularly any male that dares challenge their opinion. They usually show their "strength" by beating up people (usually men), and just being generally bitchy and opinionated.
I'll admit Kira does not fill all those stereotypes like other characters in other shows, and I didn't mean to say that she's a "feminist" stereotype. Rather my complain with Kira is with the actress, which I don't feel was able to play the role as the character required it.
Kira as a character could have been very interesting. Here we have a woman who has suffered greatly with Cardassian oppression, but at the same time is highly religious and spiritual.
I would have loved to see:
1. A realistic take on forgiveness as most religions ask of their believers (love thy enemy)
2. A realistic take on holding a grudge against the Federation, which did not lift a finger to help them when they were being oppressed.
3. Genuine sadness when required. Example: Kira's father dies and she's remorseful that she didn't stay with him but went off on some mission to kill some Cardies. Her reaction was to do the same thing again, go kill some Cardies. Would it have killed her to show some sadness at what just happened?
I think Kira as a character is very interesting, but I don't think Nana Visitor was capable of doing more that phoning in her performance for certain character traits that were needed to properly portray that character.
I'll say that this is not exclusively a Nana Visitor issue. Avery Brooks is incapable of showing anything else than brash, abrasive attitude, which works great when he's dealing with the Dominion, but not so much when he's dealing with his crew.
And I could mention horrible acting in other series also. It's just that Nana Visitor's acting is the one that seems to be defended to death. Go on the Voyager forum and you'll see a spade being called a spade (no one disagrees that Harry, or Chakotay were cardboard cutouts for example)
