It's very stylized and not really supposed to be taken seriously, even less seriously than the prequels I'm sure. I love it for what it is, but it's not really supposed to cover the same ground as the CG show. It's intentionally Genndy Tartakovsky having Samurai Jack-style fun with explosions and swords.

That said I did try to include the cartoon kidnapping of Palpatine in my own edit, but all the people around me went "BUT IT'S A DIFFERENT STYLE" and I couldn't quite get the stuff off the DVDs.
