i'd say given that arrietty isn't originally a japanese story, it definitely feels different from the others. it's got the usual ghibli style and all and it's suppose to take place in japan... but the feel is more european/american than japanese. it was good and i enjoyed it, though i wouldn't say it's the best ghibli film. it's cute though. the story is much more straight forward than some of the other more symbolic ones like mononoke, howl's moving castle, or spirited away where lessons are taught through extraordinary means.
