Princess Mononoke was great, starting right from the beginning. I really wish there were more with higher levels of violence. Though, I do prefer his allegories for War. Imagine loving planes and technology and the ability to fly, but Grave of the Fireflies being pretty much based on your life. So, you combine the childlike sense of wonder with death and violence, when it comes to tech. Grave of the Fireflies is pretty f'n sad, and then you see those hidden messages as an adult you didn't see as kid. It makes you view Ghibli way differently, both good and bad.
I'm still traumatize by Grave of the Fireflies (but it's a Takahata film, not a Miyazaki one, even if they are both Ghibli directors). Miyazaki is really pacifist, ecologist and feminist too. At the same time, he feels bad because he love aircraft (who are often machine of war and also pollute a lot) and also his family formerly owned a aircraft piece factory which participate in arming Japan in second world war.
