Toriko at least had its two great final chapter, the weeding and the space gun touched upon everything that was good about the series.
Assclass wasn't perfect but it was the series with the least mistakes
Bleach got screwed by Kubo trying to screw over the editorial department
Naruto, besides the post war orgy caused marriages, was fine, a little less good for the need of launching Boruto instead of ending, but as an ending it was OK.
I am sad that I can't remember Beelzebub ending. There was something about human generals and the demon world and furukishi and demon powered tissues and a wall of demon seals.. But nothing concrete…
