The censorship. There is a bureau named 广电总局 which censors every film. All Chinese movie directors are worried their works wouldn't pass the censor process. Hence they harmonize the movies since they begin thinking about the idea of a movie..

Disaster movies tend to show social upheaval. Movies set in the future speculate about change.

DANGER DANGER DANGER

The CCP-imposed restrictions under which Chinese film-makers operate are pretty oppressive.* Analysis and speculation (and a thousand other things) are strictly off limits. I think China could make some amazing films if creativity, complexity, or social commentary were allowed. But they're not.

*: It irks me when China tries to take credit for Taiwanese/American director Ang Lee. If he was Chinese, he couldn't have made most of his films. Life of Pi in particular.

Too much thinking not a lot of thought process....

Armageddon in China!  

That's nothing more than getting on the bus in the morning.

The world will end when China decides it will end. The world belongs to China.

China considers China as "the World".  Nowhere else exists.

If China was to make films on the subject, it would mean the end of The World (China) and this would go against all their thinking about nothing and no-one being able to beat China, destroy China, be better than China and so on.  Furthermore, they would lose face big-time, and they don't like this either.  As ignorant people go, China is a favourite for the Gold Medal.  So, really, we will never see their faces if it did happen, unless you believe in reincarnation which, because of the wonder created in my mind now, I am going to start believing in.

you will probably never see 'end-of-the-world' movies, just like you won't see time travel or sci-fi movies. They depict the possibility of things being different (better) from what they are. You will, however, see movies based on actual disasters, such as earthquakes, where there is the probability of official organisations being shown in a good light, and there is solidarity between all.

kaiwen is right chinese view getting on the bus as a life and death situation. so their disaster movie would be a series of clips of chinese getting on the bus like animals

ask a student what he thinks he or she will be doing in a decade, and get the famous blank stare, i have to teach them to lie for the ielts tests for future jobs and studies because they have no concept of this.

part 3, predicting the future, not a clue, will all text books  be on an e- reader in the future, blank stare, will cars run on water, hydrogen, blank stare.

i have no control of my life, so why should i think about it or care.

crazy foreigners, imagination about the future, who cares
