Totally agree! This coming handover will contrast with all what PyeongChang has done, and approaching Tokyo's standards. I like these sort of showing off contests. Three Olympic editions in a row will bring that, hi-tech rather than warm hospitable environment.
Rio didn't 'glorify slums'....it celebrated high rise living- a celebration of all the peoples of their great cities, from the super wealthy in their penthouses, to the poorest in the favelas. I actually thought that was rather brilliant and inclusive.
Opening ceremony felt cheaper then in Rio, but it feels it better quality then Rio imo. I really impressed with drones also great fireworks they utilized local area very well for them making very nice view and quantity was quite large.
