I just realized, this arc would have been infinitely better if Threepio were in it. Why in the world they decided to make this into 4 episodes is beyond me. It might've been ok as a two parter. I liked it at the beginning, but this was just ridiculous.
And I can't believe Artoo survived that huge HUGE explosion. That was so lame. At the very least they should have totally destroyed his body but salvaged his hard drive and put it into a new chassis.
