I'll say that FFVIII has a bad story but it does have the luxury of pacing that gives each plot point time to breathe and be filled out, even if it is all total nonsense. XV is bad in a different way. To me, it's the first mainline FF that has development that's felt extremely rushed to the detriment of the story.
I dunno, if you're only on chapter 10 then maybe you'll change your mind because that's right after the open world part, the best part of the game, and when they really just start rushing through.
