I like Miley (got teenagers at home) and Hannah Montana is a good show. But she is nothing like she is on the show in the real world. On the show she is down to earth and funny but that doesn't seem to translate in interviews.
I thought her dress at the Oscars was awful and embarrasing, she should fire her advisers. It's very hard at that age when you realise that and feel bad. (check the way she was standing, hunched shoulders trying to minimise her size)
I also thought she looked like the incredible hulk next to the other girl which probably didn't help.
She was introducing best song which did make sense and so she wasn't out of place. Just that it all went a bit wrong for her.
