Oh heavens yes! As absurd as a spiky haired kid, Donald Duck and Goofy running around in Disney worlds fighting adorable monsters with a key shaped weapon. Intermixing Disney animated style, square Enxi Anime style, and of course, Jack Sparrow.
Best piece of evidence thus far.
I think it would be very interesting. But excuse me, how is batman to dark? Please tell me how stabbing yourself in the heart, to save the love of your life and then not going home with her, isn't dark?
Oh, how about how your best friend is your enemy for most of the story?
Then there is the story of Ventus. He broke his heart to save his friends and is now in a coma!
Please, PLEASE tell me how kingdom hearts isn't dark, emo, and depressing as hell!
