The reason is, we expect more from an experience mangaka. But that experienced mangaka say that, he is inspired by Tom and Jerry. He said, he is trying to bring back that lost art (looney tunes).
He is taking the easy way out. What happens when the artist distance himself from the art?
If he was inspired by looney tunes, why he didnt start chapter 1 with eye popping out, using wheels for running and other such effects?
I will accept mistakes from a starter, honest and hardworking mangaka, but Oda is none of that.
There were so many cringe moments in this arc that made me question Oda's credibility.
Remember, One Piece is a jewelry shop. We expect to find gems in it.
What you just said about flying 6 is like you are saying we found diamond in dirt.
For God' sake Oda, you have published 1,000+ chapters, you are not supposed to be fooling around at this stage.
