Just watched the last two episodes back to back, you're right, it is like a 21st century CGI remake of the Droids cartoon series, or the excellent Dark Horse comics that came out in the 90's. They were fun enough fluff pieces, not really moving any major plot points along for the series, but a good giggle. I agree I preferred the 2nd of the two shows more too, the first was a little too whimsical for my tastes, but the second had a lot to say, with it's homage to Gulliver's Travels with the little people of the first planet, the Wizard of Oz with the second, and a non too subtle overall satirical commentary on American foreign policy judging from the way the encounters all ended up with the droids disposing of tyrannical leaders, introducing the locals to the idea of democracy and leaving the inhabitants to sort themselves out as they commence to tear themselves apart. Quite biting political satire for a kid's show. And then it ends with a take on Robot Wars with a droid gladiatorial ring aboard a pirate ship, featuring a Gladiator ASP droid (also seen in the intro scenes to Mos Eisley added for the SE of
ANH), before the droids come full circle and end up on the Separatist ship that attacked them in the first place, just in time to be rescued by a Republic rescue fleet. Practically enough content for a whole series of the Droids cartoon series all in one episode. Good stuff.
Anyone else feeling that it seems a little weird that we're 6 episodes in and have still not seen Obi-wan Kenobi? I wonder if this is just how the episodes panned out, or if it is deliberate and there is some significant plot point behind Kenobi's absence? Only time will tell.
Also worth noting is the fact that the offical Star Wars website is bigging up the return of Darth Maul, both through the release of Star Wars Episode I in 3D at the cinema next year, and his return on the Clone Wars hinted at in the last series. Should be interesting to see where they go with that.
