It met my f(x)-pectations.
The choreography is fun, I like the patty-cake parts especially, and it plays well with the song and its transitions.
The Styling is odd, as expected. Amber's sparkly eyebrow is . . . interesting. I think I kind of like it, but I'd like it better if they were even. I'm not a huge fan of the plaid sections, especially with Krystal's hat. It looks like they're trying to push a Scottish thing and the sound feels Hindi . . . is just doesn't work. And is Victoria wearing a CollegeHumor dress?
I really like the glass floor thing, that is actually really cool. Especially with the upside down and out of proper perspective elements, they really play well off the pitch-bend of the song. The rest of the sets are very generic electro-pop backdrops. Visually interesting, but nothing out of the ordinary.
Song-wise, it's interesting. The sound feels almost Hindi-pop in the intro, and a bit in the chorus. Like most recent f(x) songs it never really takes off. I like it much better than Pinnochio but a little bit less than Electric Shock. Amber's rap works really well, but it feels like the climax of the song and leaves the rest to hang. Melodically, I like the bridge and the ending, but they don't contrast with the verses well enough to make them pop.
