Nothing lazy or filler about the Theatrhythm games. If anything is slapping you in the face, it's your own poor expectations.Are people actually happy with this? This just seems like filler on never before seen levels.
I could understand they want a quick cash grab, but this just seems lazy and a slap in the face for people who are hoping for a new KH-game.
This is one of the few series that can sustain a game like this due to the vast library of quality music, it's a good use of assets and there's plenty of content.
