Back to the Flash theme, it's important to note the first version spent half its time trying to stay "domestic" without the "meta-human" side of things ... filling in gaps of normal (for then) police work.

And personally, I think this was the problem, and was what my statement was addressing. There are two warring concepts:
1. People watch superhero shows for the fantastical. Just as people watch procedural shows for the procedure, suspense shows for the suspense, etc. Agents of SHIELD had this problem during its first season. It was a spy/superhero show. But it had neither. The reason, of course we see in hindsight, is that they were treading water waiting for Captain America: Winter Soldier to drop. Then it turned into a completely different (actual) spy/superhero show.
2. People watch entertainment to be entertained. To be entertaining, you have to have certain elements. And the group of people that you have to appeal to in order to have a successful movie/TV show is a lot greater than the people that are usually attracted to your genre. When you only have a group of people that like to watch your genre watching? You end up with a cancelled series/flop of a movie that's labeled 'cult'.
