Plausibility in stories

In many/most of the stories I read, even the so called, historical ones, the burden of proof is often not satisfied. But if the tale is reasonably well written, we can like it as entertainment. That goes for written work, and movies.

A point of confusion for me, the movie, "The Good Shepherd" by EM Forster was very good, rivetingly so. I thought that he was a veteran of the Navy. Much to my surprise, he was simply a good writer. He also wrote, "A Room With A View", one of my favorite stories ever.

As part of my Corona 19 boredom relief regimine, I just watched "Independence Day" just because I liked the Actors and their performances. The movie was not plausible, but I was thrilled. Then I watched, "Star Trek, Into Darkness". Again, I liked the movie. My one caveat was that I am sure that NO Naval Officer would leave the Bridge and go rushing down to the Reactor Room to fix it. I am fairly sure that NO ONE would go into the Reactor Room, most times.

Where oh where is a Naval Bridge Officer when I need one?
