Jade was clearly one of the best in the competition, and was clearly better than Union J by miles. The fact that Nicole and Gary opted to send her home was very tactical for their own acts and it just proves to me that they aren't actually judging based on talent. My opinions of them have gone down.
And they are wondering why the ratings are rapidly dropping. It's because the judges keep sending home good acts instead of bad ones ie. Melanie, Jade.
