Yeah the "slow pacing" is just meticulously detailed bullet time breakdowns of the action. It gives weight to every step, every punch, every action.
Okay. So action is slowed down to the speed of a power point presentation, while a one-note narrator is given the reins to explain to us what's happening in intricate detail. This becomes the standard storytelling device throughout the majority of the longest arc in the series. "Show, don't tell" is subverted in a fashion that can charitably be described as unique, and the ratio of character dialogue to pure exposition sinks like a stone.
An interesting shift, to be sure. I find it bizarre, though, that some people are so dismissive of the pacing issues brought up - I mean, in what world is what I described above
not expected to come off as tedious to a lot of people? And not just in the "everyone has different tastes/sensitivities/etc." sense, but in the "this approach does a high-wire act in how it navigates storytelling conventions" sense. It's something that begs to be seen in light of what it achieves
and the risks it takes, not as this thing that should be above reproach to reasonable people.
Personally, and I'd like to see how this changes on a second watch, I found the Chimera Ant arc fascinating, wonderful, and
infuriating all at once. The narrator really, really started to get beneath my skin, and in the strangest way, that got both better and worse as the arc came to a close.
