Translation:

Flood of billions of dollars of overseas money flooding in mainly from China has led to demolition of too many charming, well-proportioned old homes and construction of too many big, ugly, quickly-built McMansions everywhere...

.... such that the resultant ugly and jarring architectural mess is useless to what most film-makers are looking for. 

Architecturally, maybe Vancouver could specialize in science fiction movies with plots about Western cities where North American drivers get transported every fifteen seconds to the wealthiest suburbs of Hong Kong and Beijing and Shanghai...
