They've done really great! I've looked around major Korean sites for reactions. First place to check is Bestiz as this is the place known to be monitored by the singers themselves. And the girls will be happy today because the response there is extremely positive, pretty much same as on this thread, that it's one of the best debut stages by girlgroup ever. Response on men's sites are even better, as can be expected. Women's sites are always harsh on idols but even they didn't have particular complaints for today's stage, with almost everyone complimenting on various aspects of the performance.
From what I can tell this group is already a top rookie success in kpop and they just need to start thinking about taking it to the next level. Now the one single negative thing said by the public is that the song sounds somewhat flat. We can understand that, Korean public want something with more impact these days. SM is aware of this now so it's going to be interesting to see how SM plans their next steps.
The girls had a quick fanmeeting after the Mucore stage, a short acct by a Amber noonie
"... the cheer was crazy when Amber did her greetings TT other members were startled by the cheer kekeke She did that Amber smile from the MV! She was smiling throughout the fanmeeting and when Krystal whispered something in her ear she nodded and lit up a bright smile... I fainted TT When Amber said "LaCha LaCha" into the mike the fans screamed "Ta Ta!!!" kekeke
When it was over and the girls were walking into the building, Amber stopped to let the others go in first, and she was patting members on the back"
"Another thing during Mucore recording, Amber was keeping eye on Krystal on stage and Krystal's shoelaces got loose and Amber sat down to tie it kekeke"
What's with these girls and shoelaces?

If its not too much to ask, would you be so kind and give me the link to that site, "Besitzt"------is it really called that?Good to hear that the response was so good.
Korean fangirls really seem to be rather harsh, arnt they? Those crazy Netizens anyway. Kinda scary......Are their greetings online as well?---------
Hehehehe--------------I just got out of bed, waited another
six hours without going on the computer (
I have such a strong willpower!!!) just to come to this thread right now. Well, actually Ive been reading your comments for the
past half hour or longer.
That alone was immense fun!Believe it or not,
I STILL havnt seen the performance----------I think Ill just test my willpower some more!
Still, reading all your comments is actually more fun anyways.
---------
But hell---------they really seem to attract alot of people, dont they. And while the main reason for that must have been Ambers character, things should have changed by now, no?
It seems as though alot of
2NE1, or other groups (dont know the names) antifans (or just people who dislike them) support them just because they serve as rivals for those other groups.
Of course that would not be the only reason.
Well--------good to see that they did so well, but Id actually like to watch their backstage interactions even more.
