I think it is important to build up a villain.
Let's take Doflamingo for example. He was never shown to be a monstrous person. Even before his swan song, he got played by Kuzan. But Oda slowly developed him into a threat through action and not hype. He made Doffy beat Oars Jr. easily, make fun of Jozu, kick Smoker like nothing, withstand three-way fight with an Admiral smiling and with every fight, we realized that Doffy is a formidable enemy. He was never hyped beyond few one-liners.
Now apply the same to Kaido. Forget all the hype. Then we see him withstanding a fall from 10,000 meters, thrashing 3 SNs, thrashing Luffy, matching BM, beating(?) Oden and we would all accept Kaido as this beast that we know he is. But Oda decided to hype him instead. If Oda never resorted to hype, then we wouldn't be having this issue. Kaido's action would speak louder than words but now his actions fail to match the words Oda attached to him.
