Congratulations, and many thanks to Rio de Janeiro, for the innovatively choreographed and beautifully executed opening ceremony for the Olympic Games, which was mesmerizing, inspiring, and thoroughly entertaining.

From supermodel Gisele Bundchen's elegant walk across the stadium floor and the first-ever refugee team to the all-green Olympic rings and the Samba, there was indeed plenty to enjoy and remember.

What amazed us even more is the way Rio has achieved it, and in such a graceful manner, when so many thought it was impossible.

The Rio Games could not have come at a worse time for Brazil, under the triple pressures of an economic recession, the like of which the country has not seen in decades, a domestic political crisis and the Zika threat.

The prospect of Rio hosting a decent Olympics once seemed so bleak that some even suspected the International Olympic Committee had made a bad choice awarding the city the 2016 Summer Games.

With Beijing and London setting a high bar for opening ceremony theatricality, few had anticipated anything this impressive from Rio. After all, opening ceremonies are increasingly costly these days with host countries competing to invest in effects they deem commensurate with the self-image they intend to project.

Rio, on the other hand, had a budget that was reportedly 12 times less than London's and 20 times less than Beijing's. It was operating on a comparative shoestring.

But the show they presented was nothing short of spectacular. Which prompted one Chinese commentator to gasp in admiration, "Who needs money when you have a conscience?"

Money does matter when it comes to hosting an international sporting event like the Olympic Games. But Rio offered a loud reminder that money is not everything, and conscience and creativity can go a long way.

Besides visuals that were hardly less fabulous than what we saw in Beijing and London, and the strong message about climate change, this aspect of the opening ceremony challenges future hosts and the Olympic community to rethink the way the world's largest sporting gala is handled.

We particularly admire the organizers' idea that it was unnecessary to spend large sums of money on the opening ceremony, when such undertakings as education and public health in Brazil are crying out for funds.

Like the "Avatar-like allegiance" to the environment demonstrated in the opening ceremony, this is a poignant Brazilian statement on conscience and social responsibility we sincerely wish will reach the hearts of all future Olympic hosts. Including those in Beijing, who are preparing for the upcoming 2022 Winter Olympics.
