High mys factor and wonderful music, but otherwise the game is disappointing.
The story just gets more and more messy, with lots of characters and nonsense terms to keep track of all parts of the main series and all the sidings. It simply cannot go on with longer, and it has gone to exaggeration to the extent that the script now feels completely uninteresting.
Even when it comes to the combat system, they have taken water over their heads. They have tried to remedy the monotony by inserting a whole lot of different game mechanics, but they have taken it several steps too far and many of the elements just feel crushed and unnecessary.
Square Enix had earned the embrace of the lesson "less is more" because, as it is now, the Kingdom Hearts III sets the bones for itself because of excessive ambitions.
