Gritty sci-fi movies... with women!

Book Chick City is having a Women in Science Fiction Week and I'm guest blogging there today about a few sci-fi movies I love that feature not only women, but my other favorite thing - grit. Head on over there and comment to let me know what sci-fi movies have stuck with you over the years. I'm always interested in hearing about movies other than the usual blockbusters, although I'm a sucker for those too.
