Was a big fan as a kid, and there are some contests that still captivate me.
But there are too many obscure sports, both new (skateboarding) and old (badminton), where the number of participants exceeds the number of fans worldwide. And China tries to rack up its tally by getting golds in the sports that nobody else cares about.
And worse, the whole site selection process is just an exercise in sending bribes to Geneva.
Best thing IMO would be a year where no county volunteered to host. Then maybe people take a fresh look, see how rotten the IOC has become.
