"Rogue One" had been re-shot to lessen the mood of the original synopsis.
What we got was a passable version of what could have been an amazing 'Star Wars' entry. The execs panicked, so changed it. You can tell, if anyone ever paid attention, that the original trailers contained stuff never seen in the film. Disney went in a different direction and so hired Tony Gilmour to do the re-shooting.
Even then, that film is 10x what 'The Mandalorian' is and they are almost polar opposites in delivery.
I think the weakness may lie in the fight sequences. At no point do I believe 'Mando' is a 'great warrior'. He just doesn't display the skillset, but he has nifty weapons that give him the edge.
At no point does 'Mando' ever display a mastery of his hand held weapons, when you'd expect him to do so.
And that, is what I was saying before, about the 'Ashoka' entry.
