There are people who watch Star Trek for the science?
It depends on what you know, I suppose. I remember the year "ER" debuted, and I loved it, so I asked my brother (an MD) what he thought. He said he bailed on the pilot without even making it to the end, because the medicine was inaccurate.
I'm not a doctor, or a scientist. But I love compelling stories and well-drawn characters. I think the idea is to make the Star Trek Science or the ER Medicine seem
credible enough that the viewer can concentrate on the drama.
