I've always thought it would be really interesting to write a show where the characters speak in a way that mimics how real human being communicate with each other on a daily basis.
It might end up being really bad and hard to watch but I think it could be a refreshing alternative to what we have now where every character is able to give an on-the-spot motivational speech with the confidence of someone who rehearsed it for months before delivering it.
Just a real fictional story that includes realistic human dialog.
