I guess the Chinese government has gotten sick of constant Dalek invasions and guys named Biff because they’ve made a move to ban references to time travel:
In a statement (available here in Chinese) dated March 31, the State Administration for Radio, Film & Television said that TV dramas that involve characters traveling back in time “lack positive thoughts and meaning.” The guidelines discouraging this type of show said that some “casually make up myths, have monstrous and weird plots, use absurd tactics, and even promote feudalism, superstition, fatalism and reincarnation.”
Isn’t socialism great? What other system of society has so much vested interested in controlling what its people think that it makes a rule prohibition the idea of time travel? Seriously Doctor Who and Emmet Brown never hurt anybody… OK maybe a few people. But those people all had it coming!
