It was a very pleasant Ghibli movie. It has a similar style of storytelling to My Neighbour Totoro and due to that fact the less you know about the movie and the story before watching the more you enjoy it. I knew next to nothing about it before watching and enjoyed it a great deal. If you consider yourself a fan of My Neighbour Totoro, you'll probably love Kokuriko-Zaka Kara (it's slightly stronger on drama than Totoro and it doesn't contain any magical creatures). Audio and Visuals were beautiful. I liked the story and characters a lot.
******* MINOR SPOILER ********
The girl showed more initiative than the guy through the course of the movie. I bet it had something to do with Hayao Myazaki being a feminist. After all, it was him who wrote the screenplay.
