That looks amazing, but it's an outlier. Certainly not the kind of thing you'll see on television in any normal capacity.
You CAN do terrific looking animation using modern tools. But it still requires exactly the same amount of time and effort in making it look good as the older tools did. The only thing modern tools do is allow for production costs to go down. It's not modern tech that's to blame, it's greedy corporations taking advantage of the convenience of that tech. Certainly, there has been good work done using modern tools. The new Looney Tunes shorts certainly look like they were made with a lot of love and care by people who understand the craft.
I hope that's the beginning of a trend, but I'm not holding my breath.
