Louis doesn't have the knack of bringing out the best in people, it has to be said. It previous years, his acts haven't won because he hasn't chosen the right songs for them - except for JLS, but I believe they were the ones making the decisions.
I don't think anyone particularly outshine the others last night. For starting performances, they were fairly basic and didn't have an amazing amount of depth. I felt like last night was just them getting comfortable with the stage and just .. well, showing off their voices, really.
