What is your most UNPOPULAR OPINION about the series? or its games?

Mine is "Kingdom Hearts should always have Final Fantasy characters in the games." I don't care if they are canon or not, i don't care if they contribute anything to the Xehanort saga. I think the FF characters add a lot of charms to the games and is a core aspect of the game's founding ideology too. Kingdom Hearts started off as a game where you can fight with your fave Disney characters in THEIR OWN WORLDS, essentially providing everyone with a crossover we all secretly wanted but thought was impossible. FF characters was a proud tradition in those games, and KH 3 not including them except only a small moment in the DLC is something that irritates me to no end, especially considering in KH 1 and 2, not only are they involved in a crucial plot of the story, but you can fight them as bosses!
