You should be happy foreign acts want to compete in Britain's Got Talent, it shows it's the biggest of all the talent shows.
However, let's not kid ourselves; Two and a Half Men are foreign, Watchingporn is foreign, Razy is foreign, Marawa (hula hoop girl tonight) is foreign, Alesia (pole dancer last year) is foreign, as was Jimmy Forde and Stavros Flatley. There's plentiful of foreign acts. Does it matter?
