@Mayobrot that's hard to as answer, I genuinely think most of his films are amazing. If I had to choose, I might pick the quite light hearted but easily the most life-affirming film I've ever seen, Our Little Sister (海街 diary). And After Life is a close second. But as I say, I don't think I've seen a Kore-eda film I didn't like so that's a tough qustion and probably mostly down to the kind of film that you like yourself....
