Chapter six marks a significant improvement over most of the previous chapters, save for the pilot, as the series seems to have more of a direction and identity now that the events at the stadium are in the past.
Platinum End seems to be hurrying from major plot point to major plot point without allowing time to absorb matters fully. It leaves a lingering uncertainty of exactly who it is intended for, apart from existing fans of Ohba and Obata collaborations.
It should be interesting how characters bounce off each other moving forward. It feels like the series is playing with some while such as how morally grey the world can truly be and the importance of family be it biological or not
