Richard, If that performance was representative of Miley's talent, then you can't really blame Lizzie for criticizing it. I realise that what Lizzie or I or the other posters here like might not be the same as your tastes, but I find it really hard to appreciate the talent that went into that performance. Often I can appreciate the talent that goes into a performance, even if I don't like listening to it, but not in this case. I will admit that this is the first and only piece of Miley's musical work that I have ever seen or heard, but I don't think I'm about to run out and listen to any more Miley based on that.
I didn't find her performance disgusting, just uninteresting.
