Not a great show admittedly and whilst I agree there is better rubbish on TV some of the people who appear enjoy it enormously and wouldn't swap the experience for anything.

There was a moment a couple of weeks ago when a girl of 21 sang with her granddad of 92, the audience were on their feet applauding and no matter what one personally feels of the performance or the show she will remember and treasure that moment for the rest of her life, long after her grandfather has gone..
Who am I (or anyone) to call them idiots?
