The catalyst of hand-drawn animation in the West and in the East.
In the West, Treasure Planet (2002).
In the east, Redline (2009).
I will dissect and make a thread of this decline, and it made Disney shift into 3d after The Treasure Planet, and the same as in the east, but not into 3d, yet into digital. However, in the east, there is hope: Studio Ponoc, the studio that continues Ghibli's heritage.
