I won't rate it but it doesn't pass for me.
I think this flashback always had some major problems in its very basis. First of all, a well-known issue is that we already knew most of what we've seen to a point of redundancy. We never needed a explicit statement about how Oden died, nor about his travel with the Whitebeard Pirates, nor about his position as a division commander, nor about his feat cutting Kaido... There were so many pieces of information we were told in advance that seeing them happen lost part of their impact.
A second problem is Oden himself. From day one I could tell Oden didn't need to be so strong and I think this flashback supported such prediction. Personally I found way more interesting the "big fish in a small pond" approach, with Oden understanding that he's smaller than he thought and ultimately facing the consequences of leaving the country as a significantly strong individual would have taken over it with no way to stop him. This was slightly worked during his journey (one of the first things he experiences is the superior strength of Whitebeard and Roger, which amazes him), but at the end of the day resulted in a cheap narrative in his conflict with Kaido.
A weaker Oden would have justified way better his dancing behavior. Theoretically it "makes sense" as we've seen it, and Oda could certainly make a case for it, but a really weak one. The problem with how those five years were managed isn't much about its core but the context. Orochi is shown to be evil way too explicitly for Oden to ever believe him; Oden has travelled too much with the top dogs of the history for him to trust Kaido; and more importantly, Oden is one of the very few people to live the most enlightening experience in the whole world, which is learning about the Void Century. It gets to a point that naivety is literally impossible, Oden couldn't be so naive anymore. Especially as a character that isn't portrayed in a childish way like Luffy but as a cynical individual who basically didn't give a shit from day one and was smart enough to write his own story. There are some big inconsistencies in Oden's character that reminds me of Sanji's arc during Whole Cake Island, when Oda forced us to believe that our cook was kind to a point of contradicting previous showings of his personality (such as Punk Hazard, Skypiea or Zou). But in Oden's case it is especially disturbing because not only he learned the forbidden truth but such truth directly involved Wano and the Kozuki heir. So an Oden overwhelmed by the circumstances, with a foe impossible for him to overcome in spite of the whole legend built about his strength, with the pressure of what he discovered yet with a close-minded personality (which we saw in a previous chapter) forcing him to manage the problem by himself would have justified better his choices, I think. A way more imperfect Oden, overall, that would have given space for the Scabbards to shine.
This last chapter we come to know that Oden knew about a supposed prophecy about the Joy Boy who would arise after eight hundred years, which again reinforces the needlessness of his individual strength. And this is because, at the end of the day, I don't understand why Oden had to be so important in every way (everybody is amazed by him and loves him for no sufficient reason, basically, to the point of cringe). He's a dead man, the ones opening Wano are the Scabbards, and this flashback the one that should have established their characters. Yet it was Oden's flashback; just think about such absurdity for a second, it's like seeing Linlin's flashback as Carmel's instead of hers, or Sanji's as Zeff's, and so on. In my ideal view of the events Oden would have followed the "big fish" thread I mentioned in a way more dynamic description of the events, with both sides clashing, Oden cutting Kaido but exhausting himself by throwing all his haki in the attack, yet giving an opportunity for the Scabbards to run away but for Orochi to boil him down. How Oda chose to narrate the events felt boring and clumsy, which leads to the following point: the absolute lack of inventiveness.
In Oden's case this is especially painful because Oda had all the ingredients to narrate his death by following a parallel with an oden's recipe. This isn't the first time he does such thing and it usually works brilliantly; for example, the Rumbar Pirates die one by one as Brook compares it to different levels of musical interpretation depending on the people involved, and Linlin devouring the croquembouch is similar to eating her "family" as they are crunchy in mouth too. It would have been really effective to narrate Oden's last moments, from the preparings for war (mise en place) to the battle (the cooking) and his death (culmination), but Oda just missed this opportunity and chose the easy way to go. This choice leads to filling more chapters with content that not only feels anticlimatic (Oden and co. getting caught and put in a cage) but also has some big issues (Oden was allowed to keep his swords in prison, was given the opportunity to trust the bad guys once again for no reason, Toki could approach him while caught, etc.). Not only that, but it takes the space of other events that we know happened (Denjiro and Ashura versus Kaido, Inuarashi and Nekomamushi fight, Kaido confronting Momonosuke...) and which I hope will be shown later in the arc.
Two big problems are the two significant forgets. First, Oden was expected to come back to Whitebeard's crew after the year with Roger; we even have the Whitebeard Pirates hoping to get some souvenirs once he's back. While I don't really find troublesome that Oden didn't try to ask for external help to solve Wano's issues (he saw it as a Kozuki thing and bringing a force like Whitebeard to Wano would have threatened the whole country), I don't buy that the Whitebeard Pirates didn't find it weird that his crewmate never contacted them after five years in spite of expecting to meet again sooner than later. It is unbelievable that the crew didn't hear about Kaido's take over nor about the bad situation of Wano as the Roger Pirates disembarked in an already industrialized country and Oden noticed that things weren't going well. And these are the Whitebeard Pirates we're talking about, who dared to face the World Government in direct war.
The second problem is that we were said that the Beast Pirates attacked Oden beause they wanted to know about the secrets of Laugh Tale. This is explicitly stated back in Zou and makes no sense for Oda to have completely ignored it. Not only that, but it is an objective mistake that damages the quality of the flashback.
The best of this flashback wasn't Oden related, which is a bad thing. I'm very disappointed with this, I don't think Oden was interesting enough to carry the weight of the flashback nor I think the events were narrated in a smart way. Things like skipping Moria versus Kaido, how Oda didn't take advantage of the battle to hint other important Beast Pirates, the almost zero relevance of Toki (I'm confident this was just setting up her character and we will see her again during the Void Century flashback, though), the weak treatment of the Scabbards in spite of being the actual protagonists of the arc, the absurdly huge significance given to Oden when he didn't need to be so strong and a weaker himself would have worked better... I don't know, it's just an uninspired mess.
