My neighbor Totoro is a kids movie and probably one of the best one there is because it's about them, it's not a princess movie, the others aren't really aimed at kids so they can't really be compared.
My Neighbour Totoro is unique. In this film kids actually act and talk like kids. It is extremely imaginative and magical while not trying to be epic. It treats the audience as intelligent, curious people, giving a lot of quiet thinking space in between scenes.
It is a masterpiece of film making. The other Studio Ghibili films are good, but Totoro remains to be my favourite.
