I jump between the Legends and New/Disney Canon continuities a lot, and they're both full of contradictions. I think there's a lot of frustration when a good concept is retconned by a mediocre concept and the insult is kind of made worse by the fact that Disney made a big show of "everything being the same layer of canon now" back in the olden days and stuff like Galaxy's Edge is sacrosanct, while comics and books always get the short stick. That being said, like. This franchise is so huge, expecting things not to contradict each other is kind of crazy XD I think people would have been less pissed if the retcon had been good, and/or if Kanan/Caleb actually looked like himself, and/or if it wasn't coming in the wake of general controversies about TBB
