Considering Brazilian reactions. Well, it's not the first time, actually. Plus Kim was the judge for Russia - Brazil semifinal (Athens 2004), Russia-Brazil final (WC 2006) and now and Russia won all those matches. Sometimes it seems that SOME Brazilians just can't admit that smb can win with them. In 2006 Fofao said that it was "just sheer luck" that Russia won WC, now Brazil lost because of judge mistake, after the match between Russia and Brazil at WGP 2007 final round (Russia won 3-2) Brazilians even didn't shake judges hands, thinking that judges did too many mistakes in favour of Russia. However, Sheilla, for example, simply told that Russia played well and deserved to win, no more no less. Ze Roberto is mad with that judge I think, because he always loses when Kim is the main referee.
If you come back a few pages you will find the same reaction here. People were telling "oh Russia is playing bad" instead of Brazil was playing good the 1st and 3rd set. I don't think Kosheleva did anything different than other games but this time Brazil had a high block and a solid defense for her. And yet people will always say Kosheleva played bad. I alwats think it's 50-50%. You will call for the team you are supporting. So you might end with something like "my team played great" or "my team played bad".
Once again I saw interviews and read reports of players giving credits to Russia but most of times they were just apologizing for the game and for brazilian fans. I don't think russians need credits for their win. They simple are the World Championship winners. What else they need?
