Imagine Goku, Ichigo, Naruto getting a powerup that turned Freeza, Aizen, Madara fights into a joke. That's what happened with Kaido, a villain who pretty much dictated the ENTIRE post timeskip.
Why would i compare it to that?
The tone of One Piece is wildly different than Naruto or Bleach, where gore and violence is much more cruel and detailed, while One Piece has always been cartoony, even in violence.
One Piece is much more closer to the First Dragonball, around the Red Ribbon Era, with a wider spectrum of emotions.
I am afraid that if you guys keep reading One Piece expecting Naruto you will get disappointed.
Luffy best hit against Lucci was a giant cartoony fist, becoming a little dwarf right after.
Luffy escaped from Impel Down with the help of crazy super weird transvestites.
I could go on all day.
The reason why One Piece is good is because it's his own thing, and that is the same reason why Jojo is good. You might not like it, but Oda writes what he cares, and the passion carries over.
