I didn't know the story and, consequently, not even the manga on which this film was based, but we have to praise that the screenwriters knew, in a simple and intelligent way, how to show us who the characters are and their characteristic profiles. In the post-credits scenes, they showed us the new characters that will come in future sequels.
One thing I miss in the vast majority of Chinese and Korean productions is the quality of CGI, costumes, and makeup that we find in almost all Japanese productions. I didn't feel embarrassed by any scene or dialogue, on the contrary, the quality of everything was great. I didn't know the "Golden Kamuy" universe, but I feel satisfied with what was presented here and I look forward to the continuation.
