There are some fabulous performers in Britain' Got Talent every year. This year there have been some excellent singers, an amazing water acrobatics group which should have won and gone on to the Royal Variety Show.
There are some odd performers: a German 'plumber' had an act of throwing sink plungers at the backs of muscular men to make them stick. Accompanied with a running commentary in German which was entertaining for its humorous delivery.
Famous outcomes of this show have been Susan Boyle and Paul Potts. And that shows the ignorance of the judges. The panel are philistines most of the time. Susan can sing well but she's not the outstanding singer that all the applause and record sales would suggest. The surprise that her voice is good coming from someone who is unglamorous gave her the fame and winning on the show. Her voice is good enough for a career but there are far better singers who would have beaten her on vocal ability.
The judges pushed her forward because of the contrast of her voice with her appearance. The likes of Amanda Holden are not experienced casting directors. With the exception of Simon Cowell none of the judges has any experience promoting or producing a new act. The panel consist of whatever well known faces are available this year.
A panel of experts who can assess acts abilities and help them develop would be better but they would be unknown and the show panders to the audiences need for identifiable faces.
Consequently many real talents and years of practice either don't apply or are rejected because the judges are easily impressed by a nice sounding but only of average quality for professional standards.
To confirm my opinion a dog won and beat the water acrobatics, musicians, dancers and singers. That says it all.
