This was a phenomenal series of episodes and the ending did not disappoint me. Did anyone else get goosebumps with Krells "it's treason then" line? Nice throwback to ol Palps. I was very pleased that Krell wasn't some double agent or something, just a horribly arrogant and disillusioned jedi who wanted to change sides. I also think that Krell surviving well makes sense in the context of order 66. He saw them coming after all, he was on the defensive, while the Jedi in ROTS had no reason to suspect that the clones would start shooting them at any given time, especially in the middle of a battle. I suspect they would not have gone down so easily if they hadn't been surprised.
Great set of eps though, I love the clones, clone centric eps rarely disappoint. They managed to take these faceless armored guys from the prequels and make each one unique in their own way, they have a lot of depth for being "identical" and it's great. It just further makes me want this show to eventually do an order 66 episode. See whats going through their minds while their blowing away their former comrades, wee them wrestle with it. My only let down was the sort of abrupt ending, it would have been nice to have the jedi discussing what the hell went wrong with this guy and how they didn't notice that this guy was such a maniac. But other than that, great. A+
