Let me agree.
Michelle Yeoh. Yeoh. Yep.
And Michelle Pfeiffer was an excellent cat woman. Meow.
Mira Sorvino did a fair job in Replacement Killers.
Pretty much anyone who has been in a Jackie Chan/Chow Yun Fat flick would do. But it doubly reinforces the point - they are JC/CYF flicks, not Michelle Yeoh flicks. And they aren't Hollywood. But I find that my tastes often run to Hong Kong over Hollywood....
Lucy Lui was pretty good in her few fight scenes in Shanghai Noon
And Geena (not Gina) Davis was also in a god-awful, but very amusing pirate movie (I forget the name - but imdb reminds me it's Cuthroat Island) and Milla Jovovich was also in The Messenger, where she was a serious ass-kicker.
I'd say Sigourney Weaver is the only real Hollywood actress that has a serious ass-kicker reputation on par with Arnie et al - Linda Hamilton is up there, though.
However (the more I type, the more I have to type), if you go to TV, you've got Lucy Lawless (Xena), and a number of actress I can't remember (B'lanna Torres from Voyager, the girl from Dark Angel, et al).
But you do have to work at it. Personally, I love ass-kicking females. I say the more the merrier.
And now I stop.
I knew I shoulda brought a crossbow.
