Good and influential female directors are hard to find.
Good however ( and possibly influential) :
Katheryn Bigelow , director of such films as near dark and point break.
Mira Nair , director of award winning movies as Salaan Bombay ( Canner award winner and OScar nominee) and Monsoon Wedding
Nancy Meyers , dorector of What Women Want and Something's Gotta give
Karyn Kusama , directed the good Girlfight and the sadly atrocious Aeon Flux
Gurinder Chadha , who directed Bend It Like Beckham
Jane Campion , who directed Holy Smoke ( 4 words : FULL FRONTAL KATE WINSLET ) , The Piano to name a few
Those are all i can think of right now , besides the one you mentioned KAne
