As a big fan of Nobody Knows, Still Walking, Afterlife, well, all Koreeda's movies, I had to go see I Wish at the theater and pay the big bucks (yay Japan 20$ for a movie).You could compare the slow pace to Still Walking,also the Kyushu scenery is beautiful and brotherhood stories are known to please people. The Koreeda touch helps to get to the innocent,Ozu-like contemplation.(not as much as Still walking probably).
