Shallow gameplay and incomprehensible plot
The initial biggest complaint is the "So, where's the Disney or FF stuff?" SEVEN hours into the game and you're still stuck screwing around with no-name characters, wandering around a forgotten area with nothing to do and little plot advancement. It just feels like pure filler - almost like a cutscene that should have been removed from the game to lesson it's length. Yet you have to "play" it - going from area to area, button mashing in the 2 or 3 encounters, doing nothing but hoping for a bit of Disney around the next corner.
Sadly, the Disney that we loved in Kingdom Hearts doesn't show up until you're significantly bored with pushing the same buttons for over 7 hours. I don't mean "your slow 10 year old kid brother who insists on reading every line of text 7 hours", I mean literally, 7:00 hours on the game time meter, pushing your X button as fast as you can to speed through the ridiculous amount of text and lame plot points that make as much sense as a book with the first 200 pages removed.
Who is this guy? Why does he care? What are we doing? Why do they want to stop us? Why is this guy helping me? Nobody knows! It's just assumed and ultimately, skipped past as fast as your finger can hit "X" because all that text and all those cutscenes really doesn't matter, nor make any sense anyway. The questions go on and on....
It's a sequel to KH? Why do I start as a kid that looks kind of like Sora? Why do I care about his friends? Am I really Sora? Wait, I'm not? Why did I spend the past 4 hours being this other guy? Where is Donald? Where is the Disney stuff? Why am I pushing X over and over again and not having to use a single healing potion or other item? Why am I still playing this?
Take away the Disney and the Squaresoft parts of the game and you would be left with an indecipherable, easy, and overly long FF ripoff. Fortutnately, if you put some time into the game you're rewarded with the same button mashing, confusing plot, overdramatic character development - but at least it's in the shiny Disney world that will make your neice smile when you start the "Under the Sea" minigame!
