I do not think you can JUDGE an unmade project… BUT…

I think the problems with RoS were chiefly thematic, both contradicting earlier themes and generally being unexciting ideas (“it’s all about Skywalkers and Palpatines”)

THIS story (DELIGHTFULLY animated) seems to have a much more interesting set of ideas and themes behind it, BUILDING new ideas, like Kylo’s downhill slide, or Rey’s new ideas on the Jedi.

And straight jacking a Star Destroyer would have been fun to see.

IDEAS are a dime a dozen (look at this website) and execution is ultimately what matters, but this sure looks like it COULD have been a fine film, more satisfactorily concluding the series.
