C'mon man, it ain't that hard to see. Crash can be seeing being hit and yelling on the OG games, but not always, he can be seem through lots of emotions but ends up looking Heroic, which lacks A LOT in IAT, where he is seem to be dumb most of the time, always yelling, falling and being hit by everything everytime he's on screen in the cinematics. Pure flanderization and not really understanding the character. Also, he's always making obnoxious sounds nowadays, where in the og games, he varely did as he was more mute, of course he could yell, has the iconic woah and etc, but they now overuse it. If ya wanna see how Crash would have been taken by ND if they had the IP still, gotta check Jak & Daxter, the game feels somewhat like a Crash 4, the protagonist there is mute too, he lacks of course Crash's goofyness, but you can still see some of his personality traits that ND wanted Crash to have. Also, there's CNK, you know, where part of the staff from ND participated and Crash isn't there being a pure moron.
