The problem with her concerts is, she just stands there, and I mean she's a pop act she should be full of energy, her voice is horrible from the videos I have seen so far, the production is cheap/boring and does not match the level of awesomeness of the songs, and to be honest, her moves they seem heavily contrived, I don't know how to explain, it's just not very enjoyable, the faces and the dramatic movements she does with her hands, she tries to be theatrical but fails miserably
But it's really cool the way she connects with her fans, though
