What are some dictatorships that didn't end in blood, death and sadness?

Today I was listening to my teacher talk about Authoritarian governments, and dictatorships and I started wondering if there were any, (if at all) cases of a Dictatorship going right. I was thinking about it because my teacher, put a slant on it. A certain bias I guess you could say. I guess I am just wondering if he is justified in the way he views things or is there actually times and places where dictatorship worked? Anyways thanks for your answers in advance! :)
