This is the best point. Do I think DSC dialog is perfect? Um, no, I don't. I don't think any show's dialog is perfect (except for M*A*S*H) and there is room for improvement.All in all, I think DSC is slowly evolving; it's not perfect but it's kinda getting there.
Now, does that mean I think DSC is unfitting of professionals? Also, no. I work in a professional setting with licensed counselors. We still have slip ups, misunderstandings, moments of unprofessionalism, and the like. We are also no written for dramatic purposes.
I think that a TV show sometimes needs a bit more latitude.
