I also don’t mind the one possible continuity error very much. Let’s just say… something something time travel something. I didn’t know about the error having not watched the entire original run in years (and even then, I was so young that who knows if I even saw them all between the first run and later reruns).
I think at worst it’s a retcon. If we are to believe now that Jack never killed any humans then it’s not hard to imagine that yeah purposefully came just short of it in that episode (it looks like they could be dead but they are all in one piece and this is a cartoon after all so people can survive a lot). The funny thing is I binged watched the whole show very recently and didn’t even notice that myself.
Binge watching was a really interesting experience for me. I was a big fan of Samurai Jack back during its original run, even though I probably only caught a handful of episodes because it seemed like it was never on. Oddly enough, back then I just assumed the whole thing was completely serialized (partly because I had seen the first three which were, and because nearly episode starts more or less en media res and I was too young to understand that concept) and I thought it was a lot darker/more serious too (probably because it was on Toonami and seemed to only be on late at night). The funny thing is that now the fifth season is pretty much what I always thought the show was, and the first four seasons were nothing more than what I always had to take it as (22 minute fun adventures).
