I've watched the last episode. And then I've seen an ending called Shinkokyu (the 9th). It was emitated before Jiraiya's and Itachi's death (including Sasuke's fights with Orochimaru and Deidara, which were quite brutal). Don't you think that estetic of anime, despite the plot, went terribly wrong? Now I see how much this series changed itself.
I didn’t even make it until the ending, I watched it to reply to this ask.
(the usual. anti-sp, anti-ending, anti-s*kura &co under the cut)
