I'm not suggesting they end it and replace it, but I am no longer in its target audience and thus it no longer can interest me. Or at least I'd like to say that is the extent of it, but I like some shows aimed exclusively at even younger audiences. Kingdom Hearts and Pokemon are two very different things, Ash is on an ongoing journey which requires some repetition in tasks but no shortage of new faces, pokemon, and little arcs, though some regulars are there to stay. Kingdom Hearts started as a boy just wanting to find his friend, but now he has chosen to tak up the sword and battle this greater evil which is just beginning to become prominent.
The next pokemon arc will involve Ash and more badges. The next Kingdom Hearts arc will involve who knows what.
Not to bash either, but they are two different genres and patterns.
I know nothing about Call of Duty, but Harry Potter is also different than Pokemon. I am no expert on it either, though.
Oh, have you read my latest chapter? I'm working on the one after it, but for now I'm really proud of how I characterized Even at least, although I'm not sure about Rinoa at all.
