Also *sips tea* The Clone Wars is legitimately great and Dave Filoni is honestly one of the few contemporary storytellers that really gets Star Wars, but the reason why he and The Clone Wars are held up as this bastion of quality for lots of toxic fans is because it’s also one of the unabashedly violent Star Wars creations in the saga. It gives the most airs of seeming adult. “This can’t be a kids’ show the girl just cut off four heads at once.” It’s why part of the reason why, in addition to nostalgia, that Ahsoka gets a pass that most other female protagonists don’t. She beheads and stabs people. She’s a violent badass. It’s Arya Stark syndrome. Notice how much vitriol is thrown at less dramatic story arcs featuring her. The violent hate felt to the (admittedly kinda mediocre) Trace and Rafa arc from The Clone Wars.
Also, you frequently hear that Rebels was holding Filoni back, but that show is just as wild and strange as The Clone Wars and arguably features better character writing. The only restrictions that Dave had for Rebels were a smaller budget, which hardly if ever actually affected the storytelling of the show, and a stricter control on the level of violence shown. This is why it gets called a “kiddy show” or why lots of older fans write it off despite the still large amount of onscreen death. It doesn’t behead, stab, shoot people to bits, devour, etc. its characters on a regular basis, so the true Filoni, the one that knows how badass Star Wars actually is, doesn’t get to be his true self.
