Genndy Tartakovsky is a truly unique creator. Samurai Jack was so good, that I had to watch how it ends years later since watching the show on cartoon network
It doesn’t appear that Tartakovsky was affiliated at all with Pantheon. I would have been surprised if he was affiliated given the show’s fairly mundane animation.
So what about Pantheon? It doesn’t seem relevant to this discussion apart from it also being animated.
