Ok after taking a deep breath, i have to conclude that the closing ceremony was very simple, but at least, well done. The fireworks, once again, were the main attractions of the show 8D, and that giant Tower of Memories was cool. Even if they didnt had much segments like the Athens 2004 closing, i think it was better.
About the extinguishing of the cauldron, it wasnt so much uninspiring, it clearly reflects a simulation of athletes leaving Beijing to an airplane and looking at the cauldron with the memories of the 16 days of competition coming to their minds. The London 2012 handover was nice, i think i put it on the same level like Beijing 2008 handover. Altough Beckham dissapointed me, ths handover didnt need him for anything.
Anyway, the games were pretty awesome, but not perfect. Cant say the chinese didnt gave their best effort on those games, and the pollution problems werent so terrible as expected (altough the rain kinda killed the mood).
