I'm surprised no one made a topic for it until you did a hour or 2 ago. (Unless it's somewhere lost in the pages of the General Discussion, too lazy for a 'search'.)
It's a good Anime, it showed the essentials pretty well. Would have expected a bit more of Amduscia and a glance of Harkotan. But it's understandable why they didn't.
The soundtrack is good. Especially love the "Brave Soldier" & "Council of Six" tracks. Oracle's "Mothership" version is done exceptionally well.
The only thing that kinda bugs me is that they didn't do Persona much justice, the fight between him and Ash was pretty lackluster and they should have shown us a bit more of Persona's timeline. I guess there was no time for it, I assume they only had 25 episodes to get the job done.
Overall a good Anime.
The best thing the Anime did, washing away the awful stench from PSO2 2016's Anime.
EDIT: Thought the topic was dedicated to the Oracle Anime, not the 2016 Anime.
