I am a Korean who lives in America and can speak fairly fluent Japanese, and it is very amusing to see TOTALLY different reactions to the scores from Korean and Japanese Internet boards. Basically, they are:
Korea -
*** Mao was overscored! She is super slow and that program is totally empty, no choreography at all. Of course she has to be able to "interpret" the program, because she's been skating it two years in a row as a total recycle. 3A? Ha, that jump isn't worth as much as Yuna's 3-3, so of course she can't expect to beat Yuna with just that jump. The point difference should have been bigger than merely 5 points. All Mao did today was skate clean, nothing more than that.
Japan -
*** *** *** *** *** (they are clearly more mad...) Granted that Yuna did well, but there shouldn't be 5 point difference between the two! Mao has 3A! That jump is difficult! Skaters should get credit for doing difficult elements!
Well, more than a few Japanese have more outrageous opinions that include Yuna buying off the entire judging panel with her sponsorship money, but I don't want to go there. I actually think both are correct, which is the most amusing part. (Now if only they will listen to each other... but of course this is Olympics and we are talking about Korea and Japan here.) Hearing opinions from both sides after actually watching the programs convinced me that judging, at least for these two skaters, was pretty fair! They are both mad, so something must have been done correctly.
