I'm American and the contestants' accents didn't bother me at all. I feel that there is a distinct pro-English bias in many of the posters. They CAN BE TRAINED. Were any of the Nancys REALLY from the East End of London? I didn't watch the show from the start. Were they the only ones worthy?
Oh, and someone better tell all those Aussies that they can't play American or British (oh, wait. They do it all the time and brilliantly!)
Good for you
