Completely agree with most on here.
The lift seemed to go wrong, I don't think she got injured, but I think it threw her a bit and she never picked it back up, kind of like when Jay went wrong and tripped, but then it bleeds into the remaining parts.
The bit on the stair when she kicked on the wrong foot, well that is something the judges should never, ever miss. There were issues throughout it though.
She seemed to flag so much towards the end and was very out of breath, it seemed she had no energy for the back end of the dance.
The flappy bird step, no bend at all in the knees. It looked so odd, she should have had a look at Jamelia's Charleston to be honest.
How much ballet did she do? It isn't touched on much, but I did a lot and other dancing and I can bend my knees into a dance, so can my pro ballet friend. Helen isn't a pro ballet dancer, so it cannot really be blamed on that and as I said, those who have done a lot can still bend!
