Golden Kamuy is a series that has a lot of potential as it continues forward to season 2. I think it narrowly missed some of the potential regarding character interactions, growth, and general direction in season 1. It certainly had some high moments and episodes, many laughs and surprises, but there was always a higher potential beneath what was portrayed.
The highest point for me (mild spoiler alert) as someone who recently played Hakuoki's numerous releases was the reveal of Hijikata being one of the main nemesis characters to the series. This tied the series into Japanese history and other popular titles in a way fictional characters simply could not.
I believe this series has the potential to be a slow-burning success, assuming the approved 2nd season lives up to and surpasses the first.
