I think it's been likened to 'car crash tv' - you know you shouldn't really look but can't help it.
I can't help thinking that the basic premise of the whole thing is cock-eyed as surely the traditional finding out about each other slowly and the anticipation, courting or whatever you want to call it adds to the enjoyment and is ultimately 'sexier' for want of a better word.
Young people today are sadly encouraged to shorten or by-pass that stage which cheapens relationships - putting the cart before the horse. I sound like my Victorian grandma, don't I? And if I was young and daft I'd fall for it. Inevitably some of the men on this programme are simply looking for a quick roll in the hay, not a relationship.
All in all, a rather sad example of modern relationships, Blind Date it isn't.
