I came here from other subreddits dedicated to TV series and animated shows I was watching for the first time, and Samurai Jack was one of those unique experiences. Unfortunately, it wasn't actually part of my childhood, but that didn't diminish the profound impact the story had on me. At first, the story seemed "simple"—it started as an incredibly cool episodic adventure. An honorable samurai trying to return to the past... and stop the great, absolute evil, Aku... As the episodes went by, I found myself getting more and more eager for the next one. And when I reached the final season, it was obviously a shock: The animation—already great—leveled up... the story focused more on Jack's psyche after those 50 years... and Ashi made a huge impact on me, too. Even though her transformation was quite abrupt, it was still really cool to see that—to see Jack with a companion by his side. And when the final episode arrived... It left a bitter taste in my mouth and a lump in my throat... Because it’s an ending that really drives home the point that... An honorable hero's sacrifice isn't a trivial thing; it's difficult. It carries weight, and there’s no guarantee everything will turn out okay. I still have my doubts and theories, But it was beautiful nonetheless. The journey was concluded, the duty fulfilled... And Samurai Jack became one of those shows that—despite not being part of my childhood— Changed my perspective on life and became one of my all-time favorites.
It’s obviously not explicitly stated, but... Taking a more optimistic view, I like to think that perhaps Jack, in his own timeline, will now age very slowly... And I believe he reunited with his best friend, "The Scotsman," at some point, living a much better life without Aku's oppression in the world. I also like to think that maybe Jack saw some of the people he had helped... Well, that’s at least how I like to see things... But I feel for Ashi; Jack really deserved to live happily after the hell he endured for years and years— frustrated, deceived, and having his hopes crushed by Aku.
