The dreaded judges

Does anyone else think that the judges on these programmes are complete idiots? The scores they give, very rarely reflect the comments they made. Is Tito Jackson deaf? It seems to me that he likes to go for the underdog. He gives great comments to the couples that can really sing but then never score them above a 5. It then comes to people like John and Jocelyn who sound absolutely terrible and they are given 7's and 8's by him. I think that these programmes would be much better if they had a panel of judges made up of members of the public.
