Rio's Olympic Games have officially begun after Friday's Opening Ceremony - a celebration of Brazilian culture featuring Gisele, carnival-style dancing and an elaborate light display.
But many were left unimpressed by the cut-price ceremony - which cost just a tenth of London's in 2012, branding it 'boring'.
Others were furious that the money had been spent on the Olympics during Brazil's worst recession in recent years.
That anger erupted into protests outside the stadium as demonstrators, also frustrated over the presence of Brazil's acting president Michel Temer, clashed with police who used tear gas on the protesters.
