sorry I missed this read and your friend is correct.

I was saying this the last few days that chapel does more medical work than mbenga and it makes no sense because she is a nurse and oh boy the mental gymnastics that people used to explain how a nurse can do more than a doctor was awful to the point of hilarious.
Also in the serious real world. this is not how you truly empower women. making women like a nurse more competent than a doctor is unrealistic. it is not empowerment, it is setting them up to fail in real life.
Sigh I even gave my own personal experience as a cancer survivor to explain how doctors and nurse do different jobs and yet all that was ignored just to defend the ''masterpiece'' that is SNW.

In the immortal words of Michael Jordan.... I took this personally.
Your friend is right about chapel but instead of me calling her a mary sue, I have constantly used the term
overpowered and she is. this makes the character poorly written.
let's take kelvin zoe saldana uhura, I am sure she can speak vulcan but would I expect her to know the language so well that she will start teaching spock and sarek how to speak vulcan? no, absolutely not and I am glad kelvin trek did not do that kind of crap with over powering Uhura.
when someone said klevin trek is empty, no I will say kelvin trek wrote the characters realistically and that makes them better.
Lastly I would not say Spock was the original mary sue. TOS Spock was just unattainable so that made him very appealing to both men and women but Spock spent his life battling is human and vulcan side. he was far from perfect as mary sue should be.
And while I will admit that kelvin trek did erase some of spock unattainability by making uhura his girl friend and giving him real pain by loosing his mum and planet, which justified some of the emotional scenes.
SNW has abused it the point that we cannot even say spock acts like a real vulcan anymore and SNW has not suffered as much as Kelvin Spock. so honestly I do want to know the psyche why some defend this because by objective standard we can see the most trek removed from canon. and it is SNW
