What I find excrutiating are the cutaways they use.
A cutaway is when the camera goes to a quick shot of a judge - and back to the contestant - it's used to edit two sections of film together.
I can only assume they have asked each judge in turn to assume a selection of expressions - amazed / surprised / emotional / shocked,
although in view of the faces we are getting, it's more like -
gormless / constipated / shot at / hand trapped in door / ready to vomit / camp / unsure what's going on ... the list goes on.
It used to be just Louie, which is fine because he is utterly meaningless, and I am unable to remember anything says five seconds after he has finished saying it, but now this has spread to all the judges.
Either it's in their contract, or they don't see the finished edit before broadcast, or they have no say in it once editing is complete - why else would they allow such images to be broadcast to a watching public?
