I don't watch much Olympics coverage, but the coverage I do watch tends to be Winter Olympics coverage and anything that is not in the hands of judge's. Gymnastics, figureskating, diving, just about anything that is decided by judges I avoid like the plague. Subjective sports tend to be very corrupt and very controversial.
Now I don't want to hear anything about how in baseball, hockey, basketball, football, and soccer that the referee's judgements are subjective and hence I'm being a hypocrite. Those subjective calls are based on rules of the game and whether the judges perceive that an infraction occured or whether a ball was in a certain location. Mistakes there tend to be those of human error based on what the referees thought they saw happen.
In the sports I am discussing it is the judge's opinion as to just how well someone performed and not whether they adhered to the rulebook that determines the winner. And, I hate those types of sports.
In the Summer Olympics, I hate to say it but only basketball holds my attention. Everything else I find quite boring. But in the Winter Games, I marvel at the skiing(slalom, downhill, and long jump especially), hockey, speed skating, and curling. Those sports appeal to me greatly. I just find so much more drama in them than anything the Summer Games has to offer.
