That means there's a lot of introspective-ish scenes of landscapes and slow-motion with music in the background, and that can be good if you're into it.
For art, the backgrounds are amazing, if only some of the craftiness of the backgrounds would bleed into the animated characters: they are so simple that it made me uncomfortable, wishing to catch some more expression and detail from their faces, but nothing. It's not something that ruins the experience, but it got in the way sometimes.
For sound, it's very good actually, good piano and classical-ish music in the background of some scenes.
The characters aren't that interesting, but they're realistic.
Overall, it's an interesting movie, that you get curious as to what the end will be, with some good scenes with nice backgrounds and music, but the story doesn't deliver in my opinion.
