Why are we so obsessed with the thought of future human despair?

Don't you just love going to the movies? A huge screen, some overpriced soda, a (semi) comfortable seat, and the smell of salty popcorn. There's only one thing that I like more than the essence of the movie theatre other than the film itself - the trailers. They tell you what movies to be excited for and what movies to avoid. Recently, though, they've been the latter. This is mainly because society (mostly hollywood) has a very recent and strange cultural obsession over human dystopia. There are countless TV shows, movies, games, and even MUSIC that all revolve around the idea of a future disaster full of human desperation and hopelessness. I went to see Dawn of the Planet of the Apes (a dystopian film) the other day and the trailers I saw made me sick, not because they were violent or scary, but because there were so many that were all exactly the same. It's such a dragged out concept that I'm so tired of. But while thinking it over in the toilet, I saw a deeper side to these unoriginal forms of entertainment. I think it's actually a good platform for looking at our society, as a mirror. We  feel watched and monitored. School shootings are normal and the people who are supposed to be in charge don’t seem to be doing anything to monitor gun distribution. There are drones in the sky. Abnormal storms happen and those in power still deny that climate change is a problem. A corrupt, multi-billionaire organization organizes an enormous sport event millions watch. Our own reality often seems like something out of a dystopian film. So I end the blog post and answer the question
by posing a different question: Have our popular escapism become nightmarish speculations of the present?
