It appears that NBC traded  in the Olympic Oaths  to make sure they got all the commericials in. Slick move
I was surprised to see USA athletes dressed  more casually for the opening ceremonies when compared to other countries. It was a different approach.
Overall I enjoyed the  opening ceremonies. I hope the games can continue without harm to the athletes and spectators.  1.5 billion dollars was spent on security alone. Let's hope the money was put to good use.
