Luffy and co standing in front of Kaido was expect and not a big deal, because that people are disappointed for chapter 1000, they expect more then this, the problem start that Oda stall/waste time the last 15chapters with stages and the roof to make it harder for Luffy, this chapter show perfect that Law was just need to teleport all important character above and save the scabbard, Luffy and co waste on 15chapters for something with Law perform in a fucking single chapter, only because Oda want chapter 1000 to let face Luffy against Kaido and Big mom.
The clash is indeed a hype but people expect it, why stalling so much chapters when you literally could end all matchups for 2-4chapters and Luffy arrive above 5chapters ago, he could easily use chapter 1000 for something far impressiv. Not like I hate the spoiler, for myself I expect God valley flashback or D reveal, both things didn´t happen yet im not disappointed because we finally get the great fight with Luffy, but other people for right reason didn´t like how Oda build this all long up.
This was like Dressrosa, chapter 750-760(end with a red hawk too when Luffy hurt Doflamingo for the firsttime) with running shit and time who just get wasted, he could easily cover everything in the last chapters in 5chapters at maximum and the story wouldn´t lose any important build up. It kinda feel like Oda just want use chapter 1000 for the encounter and he waste all the last chapters. He could done it far better.
Now it is kinda crazy how many people are disappointed that nothing get revealed and chapter 1000 is just a encounter.
In Oda case im sure in next 10chapters something gonna get revealed, sadly thing he could really done it in this chapter(1000) and end it in a big bang while Luffy encounter with Kaido already would happen 5chapters before.
