I'm watching the final episode of this arc and I actually don't hate it as much as I thought I would. It's not good, and I really miss Anakin, Ahsoka, Obi Wan, and Maul and Savage, but I thought the third episode in this arc, Missing in Action, was quite good. I actually liked the Gregor character and he was just another clone who was given a unique personality, like Rex, Cody, and the Deserter Clone from (I believe) season 2. I don't think this arc needed to be 4 episodes though and it could have easily ended after the third one, especially when there are two less episodes this season than the prior 4.
