Angry Judges!!!

so i didn't watch all of "Dancing with the Stars" last night. i only caught the last 30 min of it and saw Joey, Vivica and Mario dance. i don't know if the judges were just in a mood or something last night but Joey and Mario did great to me and i was once again bored with Vivica's performance and the judges loved it. what is going on? and what did Emmitt and Cheryl do to get them the lowest score? was there anyone that the judges did like?
