I mean, I am not against having a shorter artistic section, for example I rewatched Sydney 2000 and I know many people loved it, but it went on for sooo long. The only issue is that Rio already had a shorter artistic section than Beijing and London, but the ceremony was still really long because for some reason the arriving athletes had a slow pace and PoN was longer than usual, and then the speeches were long as fuck... and then they had one more additional speech with that new IOC award. Make the entire ceremony shorter if they want to save costs, not just the one interesting part, otherwise you are watching a 4 hours long show with about 40 minutes of unique, interesting content.
