Sounds like you too suffer from confirmation bias (your bias being you don't like the Olympics).
As far as I can tell, Paris did a reasonable job with these Olympics. The road events (cycling and marathon) were great, as were the equestrian events - both enhanced by a fantastic backdrop of historic buildings.
They did mess up the "swimming in the Seine" bit - that was a very bad idea from the beginning.
Net results of the controversies will probably be no boxing in LA 2028, which I think would be a pity.
