They just copied the original choreography of the Video Bailamos, at least in my country it is strictly prohibited to use the official choreography of a song in a dance competition, because it wouldn't be competitive at all, it would just be a dance performance. I guess the Netherlands is not good at dancing and that's why it's okay to use the prefabricated choreographies of a song. But throughout the American continent, all countries prohibit this in a dance competition, even if it is televised. They performed it well, just well, but I couldn't judge their dancing ability with that. On this continent they would be disqualified.
