I totally agree with all you write. Kim was definitely not showing her best game, especially in reception, so today it was time for the others to show that Korea is more than Kim and they did it.
And about Brazil, it confirms what I wrote during Turkey match. Most of them are not willing to work hard for success because they are too used to it. They have this attitude "we are Brazil, we are the best in the world" (their men team is even worse in this), so they are used to opponents who lose almost just out of respect, and as soon as there is more resistence than they expect, they get annoyed, but instead of playing better they play even worse and just seem to wait until the opponent finally stops the impertinence of not giving up. It's not like Brazil cannot play better, they simply don't want to, they just want to play well when the match is easy anyway and everything is flowers and sunshine. Turkey had too many problems with their own nerves to beat Brazil eventually, but Korea gave them a real bad blow today. The next match will tell a lot about the character of Brazilian players, but right now, I can see no way how they beat China...
Totally agree.
