Did you even watch the vid though, or did you just yank it from YT because of the title? Really got to try better than that. CVH usually goes into length about the specific reasons he holds the opinion, and presents it in a way that the viewer is able to form their own, instead of adhere to his line of thinking.
If you'd watched the vid, despite his personal opinions, he admits that his biggest issue with Rebels it doesn't go far enough.
The rest of the criticisms he levels at it are sins that Avatar: The Last Airbender was guilty of. ATLA is now remembered as one of the greatest western animation shows of all time, a pioneer that is hailed responsible for the current Renaissance in American animation that has led to the likes of Gravity Falls, Steven Universe, Bojack Horseman, and Rick and Morty. And you know what? One of the biggest criticisms that can be levied at ATLA is... It's a giant Star Wars homage. How about that? Rebels has much of ATLA's alumni, so it'd make sense that it would share DNA.
I did watch it. I actually don't agree with everything in it, mainly the gushing over Clown Wars, but everything else lines up with my own thoughts from my attempts to watch Rebels.
It's fantastic that you enjoy it. Doesn't make it any less Star Wars: Kids Meal Edition.
