@Mother-Vain I like the cutscenes, because it's like a free Anime within a game. It's better than what the western audience used to get with many JRPG's that had a release in NA. There used to be a time where we had less story, and cutscenes overall, in games like Sukoden, Lunar etc. If you want games with zero subplot, alongside the main plot, go play something else, because this isn't the game for you. The characters all have their own stories, and plot, many of which play out during the main quests, and later tie into the main quests.
Melrandia for instance has a series of seemingly unrelated scenes play out with Gettemhult, at least unrelated for anyone that wasn't paying attention to the fact that the man is unhinged. (SPOILER ALERT FOR ANYONE WHO STILL HASN'T PLAYED THE STORY.) He later becomes possessed by Dark Falz Elder. Even stories unrelated to the main ark, add life to the game. Such as the romance subplots at play, or the fun of the insanity that is the CAST Risa/Lisa. (Depending upon the translation preference. )
I sincerely hope that stays consistent. I'm sorry you don't personally enjoy them, but that's a you issue. Not an issue with the game. An issue with the game, would be a universal broken mechanic, that is broken to a point of it being unplayable.
