I just finished the game, without ever been into KH. I did watch a 3 hour video to give me an idea of what I'm in for, which helped a lot. I think there's few things now I have questions about, but less than I thought there would be.
However, I have a big problem with Kairi. Has she always been this useless? Here I thought the trope has died, but hey, it's 2019 and I'm still seeing this bs being done? It's almost as if they were about to give her some purpose and actual power, just to be kidnapped and killed for the sake of character progression.
Also, are all the KH games this easy? It felt a bit like a faceroll. It got really frustrating at the end with Org XIII - 1min battle, 7min cutscene. I just wanted more of these cutscenes to be in game or some interaction, it just got a bit frustrating. :(
It makes very little sense to me why the game would be so easy, as the main target audience seems to be the hardcore fans of the franchise, so it's not like you're trying to sell it to kids who are into Disney, because let's be real - they'll most likely hate it.
