I'll be in minority here then.
I played 11 chapters out of 13 as I know and it's terribly boring. There were like two or three challenging bosses up till now, and I still use auto-battle in every fight. Story is lacking, characters are weak, their development is artificial and mostly not convincing, scenario is full of errors and lacks consequence. Game mechanics and battle system is hardly an RPG. 3 stats, auto-battle all the way, limit on upgrades and linearity even there up till chapter 10.
And game's linearity until chapter 11 isn't that terrible. Sure it lacks exploration elements but on the other side, game is OK at most, so there wouldn't be much to explore except nice environments.
If it wasn't for beautiful CGI, nice visuals and Vanille's boobs, this game wouldn't have a bit of decency in it.
Unfortunatelly it sold really nice and Square decided to pull more of this crap.
Visuals: 9/10 (Superb)
Audio: 6/10 (OK. except really awesome prelude tune, the game lacks proper audio treatment. two main themes are repeated over and over, rave music in green forest, sounds sometimes are hardly fitting and not as good as the rest, uneven level of sound effects)
Gameplay: 6/10(OK. Despite boring combat system, weak mechanics, unnecessarily long battles, subpar upgrade system, gameplay is flashy and easy to follow in the beginning, and may show it's teeth later)
Story: 5/10(Mediocre. It's more like Dirge of Cerberus level of storyline. There's story shown in flashy cutscenes, some backstory to follow but it's not compelling or immersive at any point, char development lacks depth, characters are simple, scenario is full of errors, direction fails at times)
Overall(not an average of previous score): 6/10(OK).
But personally it's really disappointing.
