I liked the stuff we got with Dragon, Garp, Roger and Xebec of course, but there's a big downside to it as we don't see the other characters do ANYTHING.
Not to mention the HKs, who are the CURRENT VILLAINS each get one shot and thrown out of the picture for 98% of this flashback.
Did Oda seriously not know what to do with them? Was it hard to do something like Whitebeard vs Garling or Ray vs Garling, for example?
And he makes it clear that Gaban and Sommers know eachother but they never interacted once in God Valley..
Also, and this is the worst part of it all, he makes it so Xebec just so happens to barely survive Garp and Roger's final attack because he wants Garling to get some hype by killing Xebec off for good.
Why not, I don't know, make it so Garling fought an actually healthy and strong opponent like Whitebeard, then??
It's not even outlandish for me to want Garling to be strong since, one, Oda tells us he's strong in a SBS, and two, he's the father of the third strongest Emperor so far (a little below Kaido and Primebeard).
