Black and White's relationship is so perfectly calibrated that watching it fall apart becomes unbearable. The film trades conventional plot for the slow corrosion of the only bond either of them has, and that hurts more than any villain could. Studio 4°C's art direction doesn't just decorate this story, it mirrors their internal collapse, the color bleeding out of Treasure Town as Black loses control of himself. The pacing drags in stretches where nothing happens except the two of them existing together, which is precisely the point. By the end you're not rooting for them to win. You're rooting for Black to remember why White matters before there's nothing left to save.

Two orphan boys, Black and White, rule the streets of Treasure Town, where they are known as The Cats and nobody stirs up trouble without dealing with them first. The wild, destructive Black and the gentle, carefree White fight off the thugs and yakuza who stand against them. Their hold on the city is challenged when the yakuza move in and mysterious foreign entrepreneurs arrive with plans to demolish Treasure Town and build an amusement park in its place. With only each other to depend on, Black sets out to save the city while White tries to save Black from the darkness inside him. Their bond is strained as they come to see that the old Treasure Town may be gone for good. The film blends action with psychological and supernatural elements.
