I never saw Hondo throwing his own dudes out of a plane, but I didn't watch all of his clone wars eps.
Anyway my thoughts on the episode: the animation difference REALLY shows here. They tried, bless them, though there are some inexplicable choices like never letting Karnage fly his personal fighter despite clearly putting a lot of love into that design. The flying's good, but the pirates themselves are stiff, awkward, and the lack of Mad Dog and Weasel throws off Karnage's whole dynamic with his crew.
I have less of an issue with Dewey than some posters here and I thought the show finally sold his middle childism. Honestly his desire to be recognized is his most interesting trait, so I'm glad he had a good reason here. Dewey is a character who is all about having a ton of potential he never gets to fufill, and him leading a mutiny only to be immediately counter mutinied was pretty approprate. Something was off, but I can't complain about the moral, with both Scrooge and Dewey putting a refreshing spin on the usual trope here; Dewey owning up to being a dumbass was important, but so was Scrooge realizing he just needed to treat the kid like a person to avoid this whole damn mess.
The B plot involved Louie and Webby who are such a natural comic duo I don't feel like I need to say that it was great. It was great, Louie chastising his evil side for wimping out made me crack up.
