Thought the various Olympic commercials with the dinosaurs were rather odd. Guess it is also a movie ad but wasn't clear to me how one related to the other. NBC coverage have been good in the times I have watched, but don't watch every event. With the time difference you can already see who won online long before the show airs.
Some announcers gibber/gabber too much to fill up the air time and I just turn the sound off to watch the competition. I liked figure skating better a few years ago when the scoring was clearer. Now it seems overly complicated to accomplish the same end result.
