Kairi
Before I get into Kairi's character, let's talk about her voice actor.
I recently discovered that her original voice actor, Hayden Panettiere, wasn't even asked to return for KHIII! Fans asked her on Twitter if she'd return, but she replied "No one's asked me"!
It's not that Alyson Stoner does a bad job, but she was only brought in as a replacement before because Hayden had health problems, which is completely understandable. I can understand not being able to return because of health or scheduling problems (Like if she filming something else), but not even being asked?!
It's just like when Hideo Kojima didn't bring back David Hayter to voice Snake for Metal Gear Solid V: The Phantom Pain & Ground Zeroes. It never sat right with fans, and it led to some bad blood between Hayter and Kojima. And with good reason; he had the role for two decades!
Now, as for Kairi herself; she was given the chance to be a Keyblade Warrior, but she once again became the damsel in distress!
WHAT THE FUCK?!
