I can see where you think it's filler material, but I think it is a bit more important than that. Doffy has severe internal damage, which that's going to handicap him. Also, if Law is going to work together with Luffy to take out a Yonkou, we see how they can use teamwork. You can be disappointed with it, but I think the chapter was important for that, mainly with Doffy being weakened.
Last week I participated in the filler vs. no filler discussion, and my stand was that how could anyone think last week was filler? It had a great Law moment that actually clicked with me, Luffy's anger was getting to the boiling point, and the cage started shrinking. It was urgent, it was emotional, it was good stuff, not filler in any sense.
This week makes last week's predicament and drama invalid by page 4, Law was doing all that pretty badass send off as a cover up for some more absolutely insane shenanigans, so the emotional impact is gone, and what we get in exchange is some "glory to the Law!" panels that, yeah, looked cool, but 1-as Daz is complaining, all Law did was incredibly vague in the end. What's "destroy you from the inside", if a bit of string stitching did the job? 2-Law is just exhausted now, so we can expect more double teaming, something last week was a no-go, finally. No longer happening, as we've seen, Law can just go at it ad infinitum no matter what happens to him. So does Doffy. Do we do this for all eternity?
I mean, I guess on a visceral level this capter gave as a badass Law that's outbadassed by Doffy. Problem? We've been through this before during chapters 768 and 769, and they were better, on time, and ended on the perfect note. Law's "imma dying - no wait I can still show some more badasness, now imma dying - no, wait, I still have some more haxxness in me to show to the world, now imma dying - no wait, bullets and missing limbs are merely scratches to me" just got on a whole new level with this chapter, and as I've said, the end of the chapter leaves him. . .¿frustrated? while last week left him dead or nearly dead. Luffy last week was super pissed, this week he's badass calm. Last week Trébol was an unknown factor, this week he's a lil bitch that's in the way.
I said this was fillerish, but looking at it, it isn't. We actually went to a less tense, less climactic, less dramatic situation than what we had before.
