My Sister's Sister (2011)

This is the third dialogue rich movie I have watched this month.  I could really get used to that.  The story opens at a party to celebrate the life of Tom, who died under circumstances unknown.  It seems festive, and the first eulogy is about how amazing the dead guy is—then comes his brother, Jack (Mark Duprass).  He chooses to focus on their childhood relationship.  He comes across as childish and bitter—which does on some level fit where he is at.

Enter Iris (Emily Blunt)—she briefly dated Tom at one point, but has a great and long standing friendship with Jack.  After he kills the party, she prescribes some time in isolation for him to either get his head on straighter, or to realize that he has to fake better mental health before he re-enters civilization.   She sends him to a family cabin on an island in Puget Sound, which is appropriately isolated and gorgeous.  But there is one glitch—Iris’ half sister Hannah (Rosemary DeWitt) is already there.  She has just broken up with her girlfriend of seven years, and is well into a bottle of tequila when she gets to know Jack.  One thing leads to another, and they end up in bed together for a brief and sloppy sexual encounter.  As is so often the case when sex is involved, that one night stand becomes supremely complicated as all the implications of that night start to reveal themselves.  It is a wonderful relationship based movie that will undoubtedly be seen as a chick flick, but contains lots of good relationship advice for men as well.
