The nephews and Webby feel like they're just trying to emulate the kids from Bob's Burgers. Lots of yelling and being extremely excitable to try and force the jokes. "You used to be a big deal, what happened?" is a damn funny line but the delivery, for me, robs it of its humor. I'm sure they'll grow on me, I ADORE Bob's Burgers, it just feels weird here since I'm so used to like little kid nephews and these seem to be somewhere in the tween age range.
I've always wanted the animated shows to go back to hand drawn animation. Sad to say those days are over, its much more simplified now for better or worse.
There is always something to hand drawn animation that I really like, hard to say why. Just like it more than digital art.
To clarify you are aware that it is still hand drawn, right? It doesn't matter if it's drawn on a tablet or a sheet of paper, the result is the same. A hand and a pen on a surface made these drawings. And moreover, I doubt this was animated in America, so depending on the studio that actually animated it it's entirely possible that they were sent the boards and animatics, and then they drew the animation on actual paper and scanned it to ink and color it, which is what a ton of Korean studios do as they are dragged kicking and screaming into an all-digital ToonBoom future by Fox and BentoBox.
I don't take issue with not liking the visual style but it's disingenuous as hell to say it's not hand drawn. All 24 drawings in a second of animation multiplied out by 60 then again by 22 were at some point in the pipeline hand drawn. I think what you're after is saying you don't like the digital animation and prefer traditional? Can't say I disagree with that, even though I've seen way more fluid animation out of the ToonBoom animated Bob's Burgers than a lot of other shows in recent memory. I wonder if animation programs will ever be able to capture the look of something drawn on paper and inked/painted on a cel?
