The movie basically took everything I liked about each actress or actor and just worked on it. Zooey Deschanel is the quirky bi-sexual sister whose girlfriend is Rashida Jones who is just a straight down for any role actress and has fun with it. Elizabeth Banks plays the sexy cosmopolitan sister and Emily Mortimer is the adorable older sister. 

Basically, Paul Rudd plays the most honest and nice person in the world and during the process you think to yourself, I should be that nice. In the end, I left the movie feeling that I should be nicer to people. It was just that kind of movie. Anyways, definitely a good movie to watch.
