I’m jealous, Scipio! Very cool. I was a HUGE Mary Decker fan- but it did come out in much later years that she doped. I guess most everyone (but Frank Shorter and Bill Rodgers) did.
It looks like Rio is 2 hours ahead of current US Central time zone. So we (at least in the Eastern and Central time zones), should be able to watch a lot live.
Do you like Olympisc spoilers? In 2012, I watched as much women’s gymnastics as I could live streaming. Otherwise, I’m a big fan of spoilers, esp. in the sports where one can fall (e.g. beam, bars, ice skating.) If I know in advance that my favorite fell off the beam, I can take it better.
I don’t like any sport where pure judging is involved, I.e. Gymnastics, diving, etc. Really get turned off with judges from different countries showing inherent and blatant biases. I know it is better, but really got turned off to these sports in the 70s/80s. Sports like track, swimming, golf, etc. are all based on what the athlete does. I know team sports can have official biases (72 US Olympic Basketball Team!) but they are not solely dependent on a judge.
I watch for entertainment, I do not care much about results with few exceptions. One is swimming, just because I understand it more than other sports and the other is —Cleveland Cavaliers, who are not part of the Olympics anyway I do not understand why the team sports (like “ball” sports) are in the Olympics, they have their own much more popular championships. i just wish that we have much more swimming on TV, we can seriously watch it only once in 4 years. The best all around sport with the highest number of participants in the USA in comparison to all other sports and very inclusive. Nobody is excluded, all are participating, from the best swimmer on the team to the absolutely slowest or simply the youngest. I have seen 3 y o’s swimming in official USS (United States Swimming) completions, and everybody simply waits until adorable kid is done swimming!
Ohio: I hear you about the subjectivity of judging–it is one reason that the gymnastics disciplines came up with the new Code of Points. The hope was to make the judging more objective by clarifying and establishing specific requirements for scoring.
Also, for rhythmic gymnastics (this is new for this Olympics)–the panel of judges scoring a gymnast cannot include a judge from the same country as the gymnast who is doing a routine.
The judges take a whole series of tests, spend hours at workshops studying and going over the Code of Points to prepare for the exams. To judge internationally at a competition like the Olympics (which is the highest level of certfication) you have to pass additional exams. My kid is a national level judge (in the US) and I know that it is difficult job.
With judged sports, I keep my sanity by telling myself that the athletes chose to pursue that sport. I would guess that athletes who can’t stand the subjectivity eventually leave the sport.
One D was a competitive gymnast, then retired and became a competitive cheerleader, so she lived though lots of judging. Neither was at anywhere near an elite level and the scores, for the most part, made sense.
The other D did dance company. Talk about crazy, opaque judging. It made so little sense that we all - dancers, parents, etc. - pretty much ignored the placements. The kids did it for the love of dance. Sure, they’d be happy if they scored first or double platinum or whatever; but no one would be seriously upset if they didn’t score well. They knew and the teacher knew if they had danced well and that is what matters.
I’ve mentioned this before, but I think what would be more difficult to take than the judged sports are the ones where there is maybe .04 seconds between a gold medal and no medal at all. Where gold - or making the team - is determined by a hundredth of a second, a segment of time that most of us cannot even perceive. But again, the athletes choose to stay in those sports, so they must be able to handle it.
My local art association has award shows. I’m always surprised by people getting upset about winning or losing. I frequently disagree with the judges, but the year I was president, I went around with them, and it was interesting to hear what they saw that I didn’t.
I hate spoilers. My goal is to avoid the news altogether on days when I plan to watch. Probably harder on the west coast. 
If I know what happened, I usually lose interest in watching.
I don’t like to see the spoilers, either; it’s more exciting for me without them, and I also avoid media until I’ve seen the events I want to watch.
I really think they try to make it fair in gymnastics at the Olympic level (especially with the way they’ve structured judging, as was explained upthread). It’s not much different to me than bad/questionable calls by refs in other sports. Have I seen questionable judging in other meets? Absolutely. I bet it has happened in the Olympics, too; I just can’t remember it. It can be absolutely maddening, so I understand how people don’t like the subjectivity of some sports.
I should add that, while I’ve always loved the Olympics, and I do enjoy some sports (but don’t watch them much at all unless my kids are involved, of course–and I did watch the Cavs at the end this year 
), I’m not a big sports fan overall.
Re spoilers: never really recovered from the iconic one: hockey final, 1980.
No spoilers!
I hate spoilers…avoid media for sure.
