Resurrecting this thread after 2 years with the start of the second series
I very much like the new animation style, definitely better than the first season which looked a little to kiddy friendly. The opening is good and there is going to be some awesome action coming up.
That said, I think this new season will be a lot shorter than the first one. Season 1 covered chapters 1-297 and the manga is currently at chapter 379, so it's going to catch up pretty quickly, probably in a little over a year.
