In Her Shoes
This quasi chick flick (that even guys can appreciate) is built around two sisters with a typical relationship which is fragmented by the past and the present. Due to one large sisterly blow-out both of their circumstances change and each sister adopts a new life. When they meet-up towards the end of the movie they slowly put their past expectations and prejudices of each other aside and grow in a new relationship together.
If you feel like watching a movie with your mom, sister or grandma this movie is a great choice and one that makes you evaluate your own relationships.
