Finished it. I give it a 7.5.
Story: flaming garbage. I don't know where to even start. There's maybe a few brief moments of interest with Dion, Jill and Gav but that's about it. The whole premise is absurd on almost every level. Some of the bearer / dominant stuff could have been interesting but they shit the bed on a lot of it. I think the last fight is brilliant if you view it as a ruthless parody of how absurd FF is. Its totally cheesy and hilarious. Dialogue is sometimes pretty good but most of the time when anyone is speaking its literally conveying nothing. Its pointless gibberish that doesn't advance the story at all. I was speed reading it and skipping everything I could to get through it while reading what was said. Clive is somewhat likeable but most of the game he just acts like this invincible person that doesn't really make a lot of sense.
Game structure: flaming garbage. I skipped every side quest in the whole game except the ones you are mandated to do and I still felt the game was ridiculously bloated to the extent that I just legitimately was in shock. Every time you have to go to the hideout it sucks. I think there's literally 10 solid hours of gameplay in here that is fun and the rest is cutscenes and padding.
Borderline plagiarism: Game of Thrones, DBZ. Just to shocking levels.
Soundtrack: possibly the worst of the mainline entries. There's 2 great songs that caught my ear and that's it. To sail forbidden seas is obviously the best song in the game, which is why they used it literally on almost every boss fight which was ridiculous. Lion and the Hare is also great but its 50% an Uematsu remix. There are some others that are fine but not remarkable. Lack of live instruments on the recording hurt it a lot.
Combat: starts out horribly. Major issues with damage sponge enemies. But in the last 25% of the game you finally get enough abilities that its pretty awesome. Odin, Titan and Bahamut are the best and its all the last ones you get. Garuda is so bad it should be deleted from the game. Several of the bosses were phenomenal: behemoth, slepnir, odin, ultima. Even then you frequently had issues where it was LITERALLY impossible to see what was happening. Art style is cool but super messy in combat to a ridiculous degree.
RPG elements: I didn't upgrade anything or craft anything. I didn't grind ever and skipped as much as I could. I didn't change my accessories once. Literally none of it matters. Its an action game and all of that should have been deleted.
Art style / graphics: super good most of the time, but uneven. Limited hallways with invisible walls. Wooden npcs. But most things looked great.
They should have made this a 25 hour Bayonetta / Final Fantasy. Ignore all the side quests and like 80% of the story and cutscenes. Make more fights that are great, throw in some better level design / platforming. Expand combat much earlier. Overall I enjoyed it, but was waiting for it to be over for a long time and I felt I went as fast as I could.
