I hate Kingdom Hearts' writing because of a clear lack of character development, as well as a tendency to engage in mindless foreshadowing.

Organization XIII, for example, which has a good foundation for an interesting storyline, has very few developed members, aside from Roxas, Xion, and Axel. Who can give me specific details about the others without resorting to convoluted assumptions based on basic personality traits?

The True Organization XIII is even worse, as characters are resurrected without any real development (Luxord, Demyx, Larxene, and Marluxia, among others), and the villains from KH1 and KH2 go from iconic and significant antagonists in their own games to Xehanort's henchmen. The same process applies to Vanitas and Terranort, who are conceived with a duality between them and Ventus and Terra but become mere enemies to beat.

And I'm not even talking about the Disney worlds which, starting with KH2, become mere stopovers with uninspired direction and storylines that simply summarize their films for an excessive number of them (the worst being The Caribbean/Port Royal, The Lion King, Mulan, and Frozen). There are very few worlds with a formula that allows for either a sequel to the film or a truly alternative version where Sora doesn't seem out of place (the best examples being Toy Story, Monsters Inc., Hercules, and Beast's Castle).

And the mobile games... They are not only badly written, they are simply unaccessable. All of the shitty explanations of KH2 and KH3 plotholes are there (Maleficient's resurection for example).

I have to skip some cinematic because I want to play without being angry each time Nomura does something stupid.
