As someone who doesn't enjoy Monica I still agree with Stern's point.

Making Monica's leadership inferior to Cap's was the wrong play. She was a good leader. And its a bit insulting that other characters are dumbed down to make Cap look like a good leader.

I think they should have found a way to make her both competent and interesting. I don't like the character because I don't find her interesting...but I never found her to be incompetent. She was highly competent.
