a beautiful movie, Makoto's masterpiece, the animations, character designs, plot, the complexity, everything is pretty much perfect. All of the details in the background are perfectly animated and drawn, NOTHING was left untouched or unfinished. Even if you don't understand the movie you should watch it for the beautifully drawn scenery.
Even after watching the movie you feel this sad, crushing and empty sensation in your chest because you know that you will never see such a beautiful thing again.
