For me, the worst thing that happened, worse than scenes once again existing solely for having cool stuff in the trailers. Worse than plotlines happening and characters appearing, only to just be forgotten about. Worse than certain characters being idiots. Worse than the very blatant plotholes (how the heck can you forget that Pence is helping Sora, Ansem?) Worse than suddenly introducing a new character for us to pretend to care about. Worse than that easily missable cutscene!
No, what the worst thing was rewinding time after Sora rescued everybody. I don't know how those playing it felt, but as someone who was watching the scenes online I seriously thought the video glitched back. Like, Sora saves everyone, Kairi beings him back. The whole thing is acknowledged, and then events just...repeats itself like everyone forgot what happened.
I just don't see the point of it. Why did this happen? Why not just have them reappear before Terranort and have him get angry at their revival? Could they not afford to make another scene? Why, why, why???
^ This. How can I trust the next game will be better when this one was treated so poorly? Nomura has put himself in a bad position by rushing through the plot of this game.
