Because hes a walking stereo type. The shirtless buff guy who's the "muscle".
Then we have the "brains" who wears glasses and the most well dressed. You know because glasses and order means smart!
The "young" one who is dressed the most like a popstar and is the most excitable.
The Noctis the in between who looks the most generalized.
Plus we have the matching voices. Guess who sounds intelligent? The smart looking guy.
The muscle is all gruff. Excitable young one is the highest pitch one and then Noctis again the most normalized one. And they'll all play the same typical roles you see in any anime/video game. I can name so many characters in other media that they're basically copies of.
Well, yeah, they behave what they look like. When your personality is geared toward one way, you can kind of assume what the person will look like. It goes like that for real life as well. It's why we have stereotypes.
Doesn't make them any less legitimate. Like every other character in anything, they exist as they are. Criticizing a character for existing as they are doesn't make sense. Like, if you saw a skinny kid with glasses wearing generic clothes and he was smart, would you say that he has an illegitimate personality for being a stereotype? No you wouldn't.
It's rather about the execution and how they're handled in the story. If they go completely against their character, then that's a real issue.
Light Yagami from Death Note looked like a smart character, and guess what, he was. Does that mean it's a lazy character? Does that make Death Note any worse because of it? There's no connection.
Stereotypes don't inherently mean bad writing or laziness. It never has. Sometimes, authors deliberately include stereotypes because they're identifiable, and that's just fine.
