The filler never ceases!
I feel like I'm grading on a curve for this plot. Sure, it's original, which makes it 10 times better than most of the Disney world stories in Kingdom Hearts 2. That said, there are too many little problems I have with it for me to think it's more than bland, uninteresting filler.
It's death by a thousand cuts. Nothing here is bad, it's just mediocre all around.
