I suspect that the scripts of most TV series wouldn't stand up too well to close examination by anyone concerned with reality.
I was once returning from Paris on a Eurostar train, where the guy sitting next to me was reading through a script and making notes on it. I couldn't help reading over his shoulder and found that I was looking at a crime drama where the plot was full of holes and the dialogue was totally unbelievable. In particular, the writer seemed to have no knowledge of the provisions of the Police and Criminal Evidence Act, resulting in his police characters doing lots of things which they certainly wouldn't be allowed to do in real life.
The script was so appalling that I was finding it hard not to laugh out loud. I assumed that the guy next to me must be a college lecturer who was reading through the work of one of his less able students, since the words 'quality drama' certainly didn't leap off the pages of that script to me.
When he closed it however I saw that the name on the front cover matched the name on the guy's rail ticket and that, in front of it, the word 'Director' appeared. Above that though was the title of the drama, together with an episode number. The title I saw printed there was "The Bill" ;-)
