I never buy into the Kingdom Heart series and only finished the first game. The subsequent sequel and spinoffs are just a way to complicate storyline unnecessarily the "Japanese way". The world still revolves on the holy trinity of Sora, Riku and Kairi + bishie Axel and the Origanisation XIII. The Disney is just the convenient, and perhaps much needed offbeat setting the game use in order for it to look less generic of a J-RPG, but ultimately it still is every bit of J-RPG with dialogues and cliches as, or even more corny than that terriBAD second Transformer movie.
Erhm, to end in a positive note, that trailer for that latest installment (with title so corny, like seriously, who the hell thought "Dream Drop Distance", three of unrelated words and some of the most "abused" English words the Japanese have grown accustomed into, would make a good title?? - well that wasn't so positive) features an amazing rendition of Hikari/Simple and Clean in orchestra. Forgive me if the song has been released previously but I think I'll need it in my life.
