Wookies versus Trandosh- ans!! Hot damn!! You know, every now and then this show fulfills my fanboy dreams. The "Expanded Universe" has always said that Kashyyyk and Dosha were in the same system, and that the two races were mortal enemies because the Trandoshans liked to capture Wookies for slave labor. And here we get to see a bunch of Wookies kicking Trandoshan butt! Awesome!!
This story really showed how Ahsoka has come into her own over the last three years. It seems to me she's ready to become a full-fledged Jedi Knight. It would also make sense, because it would then mean that Anakin and Ahsoka would start going on separate assignments all the time (something they already toyed with at the beginning of this season) and it would feel a little more believable that there's no mention of her in Revenge of the Sith.
So, all in all this has been a pretty interesting season-- we did a lot of bouncing around in the time line, brought in Darth Maul's brother, met Tarkin, and explored Anakin's destiny. All in all, a very enjoyable year.
