Just finished. Jesus Christ it's the best FF story ever. I was taken aback by the nuance. I only have a few quibbles.
I think they made Emet too over the top in the Stormblood post quests. He's like the Joker. I think it cheapened the nuance and more human Emet we got in Shadowbringers, which had just the right amount of being glib.
I didn't appreciate the "fake out" plot twist where the Exarch acts like he was using you for his own ends all along and was actually evil, only for Urianger to chime in and be like "Just kidding, he's still a good guy". Cheapened what felt like would have been a more powerful moment.
For that matter, his identity was too left of field for it to have been a shocking plot twist. This was a guy with a minor part in realm reborn over half a decade ago. I didn't get it until Emet's lines after the fact.
How the hell did the Warrior of Darkness not recognize the Exarch's voice?
That's it for the quirks I had. If I have one question about the story, who was it from Emet's past our character and the other WoL were fractured pieces of? His wife?
