The only one I can think of that I REALLY liked was Bagdad Cafe.
Things like the Banger Sisters seem well intentioned but not that well executed, storywise.
any stellar examples? I guess All About Eve would be the anti-example

And a movie like America's Sweethearts doesn't really have the women friends as the sole protagonists.
So, if there's a chick-chick frined movie you loved, please post it? Any age of gal.
