You guys have to remember; that this is the last performance of the night. This audience has been thru tons of performers and are just tired. I agree she should've had more energy. But artists feed off of the crowd as a performer myslef, I know this. Its hard for one artists to get that many people hyped on their own. I think she did fine, under all that pressure. Stop hating on the poor girl, she just trying to do her thing.
