Actually completely disagree, i think where you said that impatience with Mando having no real direction is the reason why movies are short and dumb is all back to front. Mando having no real direction so far is the result of dumbing down of general audience. People see space battle, dragons, cool armour and go "whoaaaaa" and they enjoy the episodic storytelling because they lack the patience for a long well thought out story that doesn't have explosion every week (look how many said "Andor is sooo boooring"
It isn't "are we there yet"? And more "what was the point of that thing that makes no sense and contributes nothing"?
But, but, I don't think that is what is happening. It's not a great example because events were moving fast, but consider IW. In theory, you had a scattered group of characters doing their thing, living their lives, that needed to be brought together - fairly fast, since it's a film; and even then IMO IW/EG for me weren't long enough.
Because there were characters I would have wanted more of - like how BW hooks up with Cap, maybe some scenes of that group fighting terrorists (like the comics). I didn't need to see Bucky trucking feed to the goats, but at some point a conversation with T'challa would have been nice. Not to mention the IMO blip Wakanda battle.
Thanks to being a series F&F have the leisure to flesh the characters, cultures, relationships out. Like, for me, one of the best things about Winter Soldier are the conversations between Cap and Nat - in the car, at Falcon's house. The scenes aren't critical to the story, but it's like painting without using black (which adds richness to all colors). IMO Favreau and Filoni are laying pieces out, and adding details.
So when the time comes for pivotal events, there's a reason Paz Vizla has Mando's back, after challenging him to a potentially deadly duel. There's a reason Grogu is more confident openly using his abilities to fight with (which he probably is gonna need). There's a reason Bo-katan is pretty conflicted about wanting the Darksaber and ruling Mandalore (I assume there will be more of that). Not to mention, Din D'jarin is "just a guy" and as characters go, IMO he could use a bit of a break.
And for me, I enjoy wandering around the SW universe like in Rebels. New planets, new creatures, new characters. Knowing F&F have some license to do that. (One of the biggest failings in the ST was the scattershot Macguffin approach, like with that Sith knife. Someone didn't think that one through, including the effects of wave erosion on fallen debris
.) IMO one of the best things about TLJ - whether people like it or not - is Luke explaining about the Sith growing under the nose of the Jedi. If nothing else, TLJ did let scenes breathe.
So no, I disagree that all of this is happening for nothing. S1 and S2 could be more or less linear, but the universe has opened up, to the larger picture of the fall of the Mandalorians (which for me is awesome), and the Empire remnants gathering in different corners of the universe. I'm good for the ride. Also, I still want some rock crabs.
