Aside from the music, technically Kirsty just wasn't doing even the most basic elements right, her shaping was just such a miss (which was not all the fault of the music), and she did this weird thing when out of hold which I had no idea was about (prob because it was such a half hearted attempt of what it was meant to be so looked a tad strange).
I always feel sorry for celebs when they are trying their eyeballs off and yet it's just not happening. Not good, but if she stays for another week she needs to master even the basics well before she can hope to do wow performances (which of course she wants to do, but she's needs to just be realistic at what level she's at, regardless of what music is playing).
