Finale is good, though I kind of wish Kaz was in a fighter instead of unintentionally infiltrating a SD. At the same time, the character moments were more important than him being in the racer, so I'm not actually upset about it, just think it would have been nice if they could have transitioned into it somehow, such as Bucket flying into the SD hangar or something.
Depictions of the FO in the series do make them seem kind of incompetent, to the point where I wonder if anyone fighting against them might have just lucked into a win. I know it's a kids show and there was little chance of the story allowing the heroes to lose. I was a little surprised that we didn't even lose anyone, not even a droid.
I hope we get something more of the Colossus, even if it's in print instead.
