A big problem with DT17 Scrooge is that he has no real consequences for his actions.
It takes a lot from Don Rosa’s work for his characterization but ignores some things that do make that Scrooge and his tragedy work.
Don Rosa took advantage of some peculiarities of the duck comics, mostly how Hortense and Matilda are just missing. In Life and Times we see them as characters and their relationship with Scrooge, and how Scrooge’s greed destroys his relationship with them. And it is a relationship he can never get back, because Hortense and Matilda are missing in the present.
His parents are dead, he ruined his chances with Goldie (even tho there is some chance of reconciliation with that in Don Rosa’s take on the characters) but now he can have an another chance with Donald and the boys. An another chance of family.
In DT17 he has not lost anything really.
Angones said Scrooge’s big flaw was that he always believed he could ‘roll his sleeves and work to get everything back’ because 'he is Scrooge McDuck!’ and the thing is, he is right!
The world he lives in, the world of Ducktales 2017 supports Scrooge.
He CAN always just get everything he lost due to being reckless back!
No one dies, no one even ages, so nothing is lost. He can just go back home to his parents, he isn’t even really missing his youth or the chances with Goldie because they are eternally young in any practical sense.
Sure, Della was lost on the moon for a few years but even the effects of that are downplayed.
And I get why it’d tempting to ignore the downsides of ADVENTURE and be always capable of bringing side characters back to play with and that’s valid for a funny adventure show, but it’s in direct conflict with this supposed tragedy of Scrooge they borrowed from a very different medium.
They didn’t have to take this part from Don Rosa but they did while removing the impact and why it worked.
