Personally, I think that the story itself was good, albeit the surrounding thematics for the story more grim. Except the last chapter, that one never sat well with me whenever I read it.
Also, with regards to the last chapter, the tie in with the main part was the last few panels, it showed how those two were going around with that list, presumably a list of living/possibly living Nazi higher ups, Kar98k being the next one they were going to look into.
