END was just a shout-out to ENDless, but it feel way less interesting than that plot-point. Honestly it seems like END was just done for Gray vs Natsu battle.
So, we should accept Acnologia's laughable reason for being a villain because it is shounen? Or how now Erza can hurt Acnologia along with pushing him onto a magical ship.
The series is ending so I don't see how he will last until the final chapter. This fight also feels super rushed like Hiro easily could have spent more chapters developing this last stage of the series.
No one can say anything about Bleach's ending now. How did we go from Acnologia being untouchable to Erza managing to whack him with her swords with little trouble?
