Andor's slower pacing was essential - it is a character and theme driven show. That said, because it was so story driven, when big action did occur, it was outstanding because the stakes were real - none of it felt gratuitous.
Here's the kind of action I hate: Sabine bails on the big ceremony (total jerk move, BTW) and then races her speeder bike against the security ships sent to find her, culminating in an Akira slide under one. After which the security ship pilots hand-wave it all and the show moves on as if she hadn't just almost killed herself and at least one of the cops for no good reason. This just felt like action for the sake of action because it's an action show and it had been x minutes since we had some action, setting aside that it was pointless, extremely unbelievable, and made a protagonist look like a reckless idiot.
Andor's action sequences had so much build that I was completely invested, they were part of character arcs that had meaning, and they were consequential, not just to the plot but to our understanding of the characters and their relationships.
Take the final riot, where the empire confronts the seeds of the rising rebellion. By this point, we understand how these people have been pushed so far that they are finally willing to put their lives on the line, and we also understand why it matters in the greater scheme of things, even though it seems like a relatively minor event on an obscure mining world. But not only that, we see our protagonist finally accepting that he has a responsibility to take a side once and for all, through the example of his dead surrogate mother and her janky, heroic little droid. And not only that, we also see why, from the point of view of the Empire, the rebels are a scourge that must be stamped out, because we also see the riot from the point of view of control freak Dedra Meero, as her worst nightmares are almost confirmed by the lawless rebels, leaving her emotionally shattered and more convinced than ever that these terrorists must be stopped.
That is great writing: the action is totally justified by everything that has led up to it in the story, it makes sense for all of the characters to be there and react as they do, and we are emotionally invested in each of them. It shows that you don't need to blow up a planet for a scene to have powerful stakes, you just have to put in the time to invest the story with meaning.
Was there a single scene in Ahsoka that really meant anything? The plot was paint by numbers; the outcome was ordained from the first episode, and nobody really showed much character growth. Sabine begins as a character who does reckless things for selfish reasons, continues to do reckless things for selfish reasons, and the main takeaway seems to be "good job - you were right all along!" What is one thing that a character learned about themselves in the whole series? Or one theme that made you think differently about the world?
