I did. You still suck at arguing.
I stated something that can be disputed, and needs to be if you want your argument to be considered valid: "She is a 2D Character that shows little character development".
You can either disprove this by attempting to find examples where she does develop, or you can accept my proposal as fact.
Instead of responding properly, you stated an "argument" that is inherently subjective, otherwise known as an "opinion". "I think she's cute/smart/whatever". You can think she's a cute/smart/nice character with absolutely no personality, but that doesn't detract from my point.
