If you want to write it that bad, then I can say that enies lobby ended with a magic boat dying.
Or I can say that a handicap stopped the marineford war.
Not really smart to just downplay stuff by using the most retarded perspective.
The bad part about the Egghead ending (which was a very good arc up until the Gorosei arrival) was that the last 15 chapters were one gigantic stallfest.
The robot was already up and ready to use "Joyboy haki deus-ex-machina", the SHs had about 100 yards to run to the Elbaph ship and Vegapunk had to simply drop his "the world is sinking" revelation (broadcast was already up and he didn't say more groundbreaking stuff anyway).
I repeat: It took Oda 15 chapters (one and a half volumes!) to execute those three rather quick/simple plot points.
If we're being honest, that's content for 3-4 chapters maximum, but nothing more.
It's like he decided to put in the rest of the Gorosei for whatever reason and then realized "Fuck, now I have to drag out the arc finale, because it looks weird otherwise ... but I don't have more plot points left!!!!"
