Horrible, boring movie. The biggest problem was the details. Parents don't have dinner AFTER they put their kid to bed. Sisters do not know, by a single look on their brother's faces, when they are reliving a sexual experience. People don't walk into houses and not close the front door. Women who are 6 months pregnant (the sister was 13 weeks when the brother moved in and it was "almost 3 months" later when they went to a club) don't have flatter stomachs than non pregnant women. The whole movie seemed like it was written by a hermit who never had any personal relationships, he was just guessing what it would be like to have a family and friends.
