Movies on the need for independence, solidarity, twisted family dynamic (sisters in particular) and isolation?

Any movies with any one of those themes or subjects will do. I'm writing a screenplay and need some movies to inspire me!Movies on the need for independence, solidarity, twisted family dynamic (sisters in particular) and isolation?
i tend to think towards the new movie My Sister's Keeper.Movies on the need for independence, solidarity, twisted family dynamic (sisters in particular) and isolation?
Try these:





The Royal Tenenbaums


The Squid and the Whale


White Oleander


In Her Shoes


Margot at the Wedding


Rachel Getting Married





The last three movies I mentioned are particularly good with the isolation, twisted family dynamic and sibling rivalry between sisters.
