Sorry, if you don't realize how rushed this ending was, I don't know what to say.
It's not about the previous 145 chapters, it's about the totally anticlimatic way this final battle against Kaido ended (and in a lesser way the Law/Kidd, Zoro and Sanji fights).
It was like Oda slowly built up everything and then simply didn't care anymore and went speedrun mode to finish this arc.
The ending of the raid was so bad, that even most "raid will succeed" fans thought this just wasn't it and that there were a few more chapters of the grand finale coming up.
Instead Oda just makes a short time-jump, skips around 20 still open plot-points and now is about to start a totally new saga in 2 chapters after his hiatus.
