I remember when this game was announced. Back then, it was just a teaser trailer (One that didn't represent what the game would become) and an idea to us. Jpop and "Persona-y" wasn't really what came to mind - so when the game changed to what it is now, a sort-of niche style and presentation, it certainly surprised a few people. I personally don't have anything against the game, but I can see why some would be disappointed by it.
