Not many female directors prominent on the site,from what i've seen,so here are some films  which should be worth considering(in no particular order).I've certainly not seen them all(so the list is based in part on my reading and on other critical opinion),but i've asterisked three i'd especially recommend,which may not be very well known.I'd be grateful for opinions on films by women (the best/most overrated/personal favourites)-whether on my list or not.This at least may highlight some excellent work.
