I dont usually watch it but caught last nights.
I do get the impression that some of these acts have already been signed up by Simon Cowell and the panel are told to praise up any acts he has an interest in.
The last act last night was the females playing Live and Let Die on electric violins etc.
I did not think they were that good.
The fact that they were young women, all fairly attractive, with long legs and shorts skirts, went a long way towards them winning.
You have to say if they had been 50 year old men (or women) playing the same song in the same style they would not have been so popular.
Dont trust Simon Cowell, he has got very rich by being very devious.
