The Opening Ceremony commentary was simply horrific. Okay, it's fine when the athletes march in, to explain who they are. But during the musical and theatrical numbers, just SU please. Especially since Russia did an excellent job of presenting their culture and music in a short period of time.
The timezone aspect - no one's fault - is simply a crusher this time. Oooh, you can watch
live at 3:30 a.m. - gee, that's a help.
That makes it necessary to avoid Google New, Yahoo News, etc. etc. if there is an event you want to see later unspoiled (for us that is Alpine Skiing - we've even attended a World Championship in the past).
So, we've been relying on the filtering done by the Prime Time show - even though there are some automatic spoilers - for example, if anyone other than an American has a biographical feature, you know they are going to win the gold medal that night.
