The series had a really strong first and final arc. I really have a soft spot for the junior members of Log Horizon so I was particularly pleased with how the last arc turned out. Not to mention Akatsuki's sololoquium towards the end. If there is one thing Mamare is really good at, it's at those solo, rousing speeches (his "
I am human" speech from Maoyuu ep 9 still gives me literal shivers everytime I listen to it. Same with Williams rally speech During the raid in Log Horizon S2), and we got a little bit more of that this season via Akatsuki, not quite at the same level but good enough.
All in all the season was solid. As usual the production staff seems to hate the Kanami segments, but what are you going to do.
