The secret world of Arrietty is a sweet, happy and kind of sad movie. As usual Studio Ghibli did a wonderful job putting together not only a beautiful looking movie, but, a good story for all ages.
If you have kids or enjoy a well detailed story. I seriously encourage you to check out this movie, or, any of the wonderful movies that Hayo Miyazaki and studio Ghibli have put out so far. For a short list there is always My neighbor Totoro, Ponyo, Porco Rosso, and Sprited away. all are wonderful movies that are great to watch at any age.
