Stylishly drawn and beautifully painted, this cartoon by Genndy Tartakovsky who points out that cartoons people like us grew up with (I'm looking at you Super Friends) actually had very little action, so he wished to make one with plenty of it, but at the same time not being a spastic mess. He definitely succeeded. This is a story of a samurai with a magic sword dedicated to destroying a great evil named Aku (Japanese for evil). When originally fighting the creature, the shape changing alien Aku used his magic to send the young samurai into the future, thereby ensuring there was nothing to stop him from world domination. Now the samurai, who goes by the name Jack, travels the world righting wrongs, fighting the forces of Aku, and seeking a means to return to him own time and defeat Aku, thus undoing all his evil. Here are the huge problems I have with the cartoon: Jack often sacrifices himself to do good deeds at the expense of accessing time portals, but the whole point is that if he can return home the future he is in will not exist, making the sacrifices meaningless. But hey, it's a cartoon. That's what brings my second problem and I don't remember seeing this now common trope before this point. Just about all the bad guys on the show are robots and Jack chops them up relentlessly. All that's fine, after all, they are just robots and so violence against them doesn't really mean anything. The trouble is that these same robots have personalities and survival instincts much like anyone else (and often look more human than the life forms now running around our planet), so doesn't that make them "real"? I wonder if seeing constant violence done again others under the excuse that they aren't "real" as it's just a cartoon might have negative consequences. It reminds me of the Star Wars' prequels wherein robots and clones die en mass but they all have distinct traits just like any individual. Anyway, it is a fine cartoon and I wonder why it ended.
