The opening ceremony this year is great ! Everything was shown during the ceremony, from the landmarks, to the artists, songs, culture, technology and everything. It was totally cool. And the olympic games went perfectly. So many records have been broken and there are many achievements for many countries participated. And the closing was fine, but I think there're too much of singing, but it's just an opinion. Overall, it's been a great olympic and I will surely wait for the next one, in Brazil, right?
