The brides grade four aspects of the wedding.
From the editing of the soundbites the program paints them as self-centred and snakey and I have come to the conclusion that all these women are snarky bitches. They whinge about aspects of the weddings of the other brides. Complaining about parts of the wedding which they don't see as being "traditional", or fitting in with what they like. Moaning about the length of the ceremony or the content or conduct of the ceremony. Saying they're bored and didn't have a good time at the wedding.
Perhaps if they had a connection with the person getting married and knew some of the guests, and if they bothered, maybe they'd find that it was a "good wedding" and fun.
Meh, it's only a television show.
Anyhow, so you can have a laugh on me!
