After season 3, we are going to be almost exactly 3/4 the way through the manga, so you wouldn’t have much left and could probably knock it out super quick. I know the manga ending gets lots of shit from people, but I really don’t think it is half as bad as its reputation. When the final chapter came out, I wrote my thoughts about it at the time (spoiler warning).

That said, the anime has been an absolutely stellar adaptation; the kind that I could have only dreamed of. So, I don’t blame somebody for wanting to experience the anime blind, because it has been excellent from beginning to end.
