I have pretty similar sentiments regarding Rebels. The best part (other than small scenes like the last one I posted) is the interactions between the Ghost crew. They made a good decision in starting small, working on characterization and depth, before adding in more pieces of the galaxy as a whole. I liked the episodes with Saw Guerera, where it ties into Rogue One and starts to make the formation of the Rebel alliance in Canon make sense.
But theres a lot more I don't like. You see what I meant when I said this was more "made for kids" than TCW. There's a feeling of less logic to characters actions, and a lack of depth beyond "Hey, we need to do this thing so we're gonna go to this place and do it!". It was on Disney XD after all. This was also Filoni's first project after the canon reset, where he could really start doing anything he wanted, and it shows.All the force sensitive animals, space whales that can travel to diffrent galaxies, time travelling temples etc. The whole Ahsoka/world between worlds thing really pissed me off, because here you have Filoni putting time travel into star wars, not for a grand story, but so he can reach in and grab his Mary-Sue character out of a guaranteed death situation. The amount of leeway Filoni's favorite characters get is exhausting, I don't know if you saw the episodes where Rex and Wolf somehow got their inhibitor chips out, didn't kill any jedi (they're still the good guys!) and are now still somehow in fighting shape even though they should be old, decrepit men due to the excellerated aging.
Thrawn is the best and worst parts of the show. The level of strategy he brings he is MUCH needed, but it's such a sad bastardization of the character it kind of falls flat. In the Heir to the Empire novels, Thrawn is a master strategist who almost singlehandedly brings the New Republic to his knees. As you get further into the books his plans start to come into fruition and you get "holy shit" moments as it all comes together, really making him feel like the master strategist he is. In Rebels, he's chasing around a ship full of mostly teenagers, getting outsmarted week after week, only for him to go back to his seemingly endless drawingboard and come up with a plan for next week. Makes him feel like a cartoon (pun not intended).
