CMV: Sci-Fi has gotten too negative

The future is full of bright possibilities, not just dark corridors full of monsters. Not just disasters on a vast scale. Not just dystopia.

Some of the most successful Sci-Fi was positive, like Star Trek, while Star Wars balanced light and dark with gleaming rebel ships and beautiful exciting worlds successfully fighting back against evil. But all we see now are bleak futures. Even great films like Gravity focus on things going totally wrong.

I’d like to see a story set 50 years in the future in which things have improved as much as they have the the last 50, but conflict arises when some people are afraid of a big new innovation. The good guys win and the improvement is enacted, making things even better. Surprise the audience with positivity.

I think you've overestimated how positive old shows were. Star Wars was a story of mass genocide, societal decay, and mixing evil and good. The premise of Star Wars was that the whole system needed to be destroyed and rebuilt by Dark Side Anakin Skywalker, because the old habits of the Jedi and Sith needed to be removed. Star Trek was supposedly the end result of years of nuclear war, internal genocide, and fighting over resources. 

Also, all stories are based on fighting something that's gone wrong. The bigger the problem, the easier it is to write the story. A film about a mild shipping problem with a batch of healing nano-bots isn't as engaging as a film about a shipping problem *and* corruption.
