I dunno; FF12 really shows how its an incomplete story.
Everything regarding Cid and the Occurria is just so forced. Cid's a nobody character until you meet him then he's OMG BIG VILLAIN! ...who has 2 more scenes and then he's done. And they force that Balthier connection too (I stand by its forced; yeah, he eludes to it earlier, but egads do they do nothing with it. The actual conneciton felt pointless too; the whole "he's stuck in the scenario cause of it!" I don't buy since Balthier shows no signs of actually being trapped.)
(and note I purposely avoided mentioning what the actual connection is for spoiler purposes; being vague = good in these scenarios!)
I mean, the last dungeon (or rather, the 10 minute teaser leading to the final boss <.<) of the game really felt on par with the first quarter of the game (Eg where there was actual plot); suddenly Vayne's being a political threat (with Venat being forced in so he can pull ANOTHER SUPER FORM! Really, though, going off what the plot was like, they could have just pulled something like ULTRA MANUFACTURED NETHICITE MODE! and avoided using a cliched plot failure like Venat), there's actual character interaction, Gabranth is IMPORTANT again, and by extension, Basch's role is restored (Basch really was somewhat important...just then FF12's plot went under the rug, and only Ashe mattered *sighs*), what have you; this ending part is actually well done, cause you know, it was the intended ending. Just the stuff between the Leviathan blowing up, and the ending arc was clearly rushed together just cause they didn't know what direction to go in, firing the original writer and such, etc.
Really, pretty much everything, plotwise, after the Leviathan fails, barring Al-Cid. Well, Cid himself isn't too bad, but his role is just so forced (he has good VA though)...pretty much like everything.
This is why FF12's plot kind of fails; it does a pretty good job early on, but then drops it and instead of trying to continue en route with how the game use to be going, they just delve into tropetastic elements to push the plot along.
