Darker than a Bog Invasion causing billions of deaths and almost wiping out every race inthe Alpha and Beta Quadrants?
Darker than political assasination to manipulate trends in a war?
Darker than genocide?
Darker than Section31?
After 9-11 [ONE terrorist attack that was massivly milked to death by tv and drama] they all became obsessed with darker themes in shows.
Please no we've done enough darkness, we need to go back to the optimism, ask most people why ST appealed to them they often say it was the brighter vision of the future, the 21st century is starting to look like the dystopia from the RoboCop movies so there is a demand for a vision of a brighter future.
With a world now filled with austerity, famines, economic hardship, mass unemployment, rising gun violence, wars etc people don't wanna turn on their tv and be slapped inthe face with the idea that things are going to get WORSE as time goes on. Espechally since the economic end of things is going to get much worse within the next few years before things rebound and society demands a diffrent way of doing things, its more important than ever that a positive vision of the future be portrayed.
