First of all, 10 is the highest grade here, and it is impossible to grade this piece higher, but also impossible to rate it lower. Why? It has a certain something, it tells you what it's got without words, you understand everything because at some point of your life you were in a similar situation and probably only know in retrospect what evil little things you could have done to get the satisfaction you never did. Watching this will filter out all the 'real world' out of you and essentially you become a child. You understand, but more emotionally than rationally, twists - sometimes incredibly simple - surprise you, but never leave you hunger for something more, like after watching some high profile Oscar-material drama.
Those cartoons give you inner peace and happiness that very very few other movies can, it's for all ages and you can look at it from different perspectives.
