I was originally drawn to the show due to its being advertised as relating to K-Pop. After beginning watching it, I soon realized the only relation it has to K-Pop is the foundation of the show (albeit a very tiny foundation) and the source of around 3 posters in the three girls' bedroom. This I decided to accept with disappointment, and trudged on in giving the show a chance.
I only managed to watch the first season, because I couldn't bear to continue the atrocity.
To begin with, the main character, Sun Hi, is a rude, self-absorbed, absolutely unintelligent girl. I understand this is a tween show, but none of the tween shows I grew up with, such as Zoey 101, iCarly, and Victorious had such terrible role models as their main characters. Corki and Jodi are great, but Sun Hi's treatment of them is fueled by her constant need to shine and be the star of the show. This brings out Sun Hi as a terrible model of a friend. My own mother criticized my admiration of Carly from iCarly thinking she was obnoxious. Carly is an angel compared to Sun Hi's character.
I gave the dialogue and acting some leeway considering it's a tween show following in the footsteps of iCarly and Victorious. I also understand that in one season, character development is not something to be hoping for, but to be fair, iCarly and Victorious were much less disastrous.
I'm all for girl power, it's not a bad thing. But the estrogen and female hierarchy is overpowering in this show. Half of it is the three main girls competing with the senior cheer squad. There are two prominent male characters, but they're both so minor and operate as clowns for laughs. They don't have to be Asian (although that would certainly help the racism prominent in the US), but the male roles should, forgive me for a lack of better words, have a bigger role in the show.
Lastly, I'll admit, the songs are catchy and pretty good. And the choreography is also reasonable and acceptable. This is why I gave the show 4 stars, and not 1 or 2.
In conclusion, although the show has a select few positive attributes, it serves as a horrible model for teenagers, and has more than a few things to be fixed or at least alleviated.
