Shouldn't have bring all Gorosei here, not only makes them looks bad but also hampers the plot and writings
Kizaru + Saturn as main villain should be enough, focus some good fight between Kizaru/Saturn vs Luffy and Giants/Bonney, VA vs other SH.
The arc would have been at least 10 chapter less and we've could have gotten a better endings..
After cementing Saturn as the main big bad evil and showing all what he has done. Big diassapointment that Saturn is completely OK, he doesn't lose anything here, Vegapunk is dead.
All the chapters( 20 chapters worth) dedicated to Bonney and Saturn story is a waste at this point.
