I'm probably giving it an extra star but it is a breath of fresh air.

Exceptionally well-paced look at parenting and love, in a humourous extended family vacation set at the grandparents house. Dan struggles to communicate values and patience to his adolescent girls while falling head over heels in love to an unavailable woman. Several scenes and plot twists are manipulated for the sake of the story, but overall it's a refreshing and smart movie for all ages. Diane Wiest is outstanding as always as well.
