The only thing I didn't like was that hurried Gonzo-style ending. That and not seeing anything from Claus's story... The story clearly gave for more, but unfortunately it wasn't used as much as should...
The ending buildup is shit, that's real as fuck. However the ending is honestly pretty good. Would love for this series to be continued, but seems like most key production people left Gonzo/Kai already at this point and the risk of them butchering it (More than Gonzo could HISTORICALLY) is pretty high
