That wasn't what Jericho was. The first press release regarding Jericho was put out in December 2005 and this is how Jericho was described:Actually I do like the two shows Grey's Anatomy and Desperate Housewives because they are soaps . But when I watch a good show like Jericho about the nuclear attack of country orchestrated by a corrupt government official- ala Cheney look alike, I do not want to see a lot of soap opera plots that get in the way of the story telling.
"Jericho" then is detailed as a high-concept soap about a small town in Kansas that's dealing with life after a series of nuclear attacks destroys most of America's big cities.
And that was the only thing that gave it much of a chance of succeeding AFAIC. I suspect what you might have wanted Defying Gravity to have been would have been incredibly boring to most folks who loved Defying Gravity.Another example of a "sci-fi " show that was nothing more than a soap opera was "Defying Gravity" on ABC.
