I completely understand what you guys are saying. But though I'm also beyond done with flashbacks, the point was to introduce a new audience to the coming Wano arc. Not crazy about them recapping even the tiniest bit of Whole Cake Island due to it just ending, but the theme of the flashback was to catch new viewers up to speed on Luffy's involvements with both Big Mom and Kaido. Like when I first saw the Fishmand Island flashbacks and the Punk Hazard flashbacks I couldn't see the flow of what they were trying to do, but then realized they were trying to give a 10 minute digest on what Luffy has done in the New World to get mixed up with Big Mom and Kaido - who were both shown at the start of the episode.
MVPs in flashbacks were Doffy and Katakuri as brief as they were.
Now, hopefully that's it on the flashbacks. What else even is there to rehash? Oh wait, next week is a Sabo episode. I hope they don't start recapping Sabo's adventure with the Revolutionary Army.
EDIT: I don't even need to rewatch to make a list of the arcs recapped. It's pretty straightforward actually.
-Fishman Island
-Punk Hazard
-Dressrosa
-Zou
-Whole Cake Island
Basically everything relating to Luffy's clash with anything related to Big Mom or Kaido.
