Because it isn't intended for you. You won't get into this for the same reason you don't wake up at 6 am on Saturday mornings to watch cartoons (do kid's still do that? Or has the CN and other channels that air cartoons during the day killed the Saturday morning cartoon?). This show is not aimed at you. I think too many older SW fan are taking this show and looking at it as if it were made for them. A very exaggerated comparison, but it is like a paleontologist watching Barney and Friends for the first time, and feeling disappointed that the show's depiction of dinosours was not very accurate, and that it has very little to offer paleontologists or people truely interested in learning about dinosaurs. That is totally missing the point. Clone Wars is very clearly aimed at young kids, and for what it is it is doing its job. It doesn't have to fit into canon, or make sence, because that is not its purpose, its purpose is to amuse and entertain children.
Ah, but it's pushed as being part of the canon, so it has to be judged by that standard. If it wasn't, if it was just this kids tv series that wasn't taken seriously as part of the canon, didn't have a big screen movie pushed as real Star Wars and was just part of the ordinary EU... then it could be treated as just a kids show with no big issues. But it IS being pushed as canon, with a big screen movie pushed as real Star Wars, so it does have to judged by that standard. The original Star Wars wasn't aimed at only kids. It was general audience. Anything that claims to be real canon Star Wars should go by that ground rule. If it's just aimed at little kids then it shouldn't be pushed as being the real thing.
And just because something's aimed at kids doesn't mean it should be dumb shallow crap. Kids aren't all morons. I gave the example of The Hobbit, a quality book that was written for kids and wasn't dumbed down or otherwise made crappy as part of making it appeal to kids. People should make quality for kids, instead of taking the lazy route and churning out crap under the assumption that it doesn't matter because they figure kids can't tell the difference.
I don't think it is very fair when people attack The Clone Wars so harshly. It is what it is. A kids TV series based off a successful but lame series of modern sci-fi films, which in turn was a spin off of some successful and well done older sci-fi films. I think some of us are just getting into the habit of attacking anything new with the name Star Wars on it, regardless of its merit. The Clone Wars is achieving what it set out to accomplish, no matter how good or how bad it does, some of us will tear it apart. Tons of good movies have silly kids shows based off of them. Where is the dissing of Star Trek: The Animated Series, Return to the Planet of the Apes, Ewoks, Droids. All those were some pretty crappy cartoons, but we have always managed to write them off as, "just for the kiddies". Why not this treatment for CW?
Simple, nobody's pushing Star Trek animated or Ewoks or Droids as serious canon. Whereas The Clone Wars IS being pushed as serious canon. When that movie came out I read multiple reviews arguing how it was real Star Wars, and in a statement in 2008 Lucas made it clear he considers the tv shows (by which I think he means this and the live action show) to be part of HIS Star Wars universe (as opposed to the EU), clearly what he considers canon. Once it's being pushed as real Star Wars canon it has to be judged by that standard. It has to live up to that standard or be held accountable. That's what's pissing people off about it. Because we're getting told this is the real thing, this is the holy writ, this is real Star Wars like the OT. A silly kids show shouldn't be pushed as being real Star Wars. If it wasn't we could let it be, but because it is we're forced to take it seriously and take it into account and we can't just dismiss it as a harmless kids show and let it be.
its purpose is to amuse and entertain children.
I think its purpose is to make money from children and turn a new generation of kids into dutiful followers of The Great Lucas.
