I watched a lot of the sports events (both ones that I am familiar with as well as some that I am not) and the closing ceremonies. I missed the opening ceremonies but would have watched it if I had remembered.
I try to watch the opening and closing ceremonies and as much of the sports as my time will allow. After all, we only get to see each of the two types (winter and summer games) every 4 years.
The opening and closing ceremonies of the 2008 Beijing Olympics were some of the most beautiful and impressive that I have ever seen in my lifetime. And I’m not sure that they will ever be that good again, in my opinion.
