Cool thread - I haven't read or seen the series that got this started, but I have read some stuff that has good strong women as lead characters...
Kristen Britian's Green Rider series is full of strong women (not to mention they are good old fashioned page turners). It is set in a medieval type society, but gender roles are definitely not medieval.
I love Sherri Tepper - who couldn't be called anything but a feminist... most of her books center around either a strong female lead character or upside down gender roles.
Elizabeth Moons trilogy about Paksenarrion was quite good and she certainly qualifies as a strong woman.
and just for fun.... Scott Lynch's Gentleman Bastard series, while not particularly being about women or featuring them (but certainly the ones who appear are neither weak nor taken advantage of...), just because it is one of the most captivating pieces of fiction that I have read in a long, long time. He's got a real way with words and images.
I have to admit I do love Tolkein - though really just the Lord of the Rings... most of his other work I find rather like reading a history book - dry and dull.... Maybe it's just because I really started there - I think I was only in 5th grade the first time I read them, but every once in a while I still feel like pulling them out again.
I'll even admit to liking Anne McCaffrey - though I think her books generally read like SF romance novels.... guilty pleasure I guess... but her characters are always so likable, even the prickly ones.
