I love Loïc Nottet's song; it's one of my favorites. His voice, song style and even his look stands out for sure; to me he looks a bit of an alien :) The performance itself is not very impressive, not much action on the stage. The backing vocals are acting as dancers as well and everybody's vocals are good, can't criticize it.
The movements are very minimalistic, sometimes it's just the shoulders that are moving, moreover not very confident. The background effects are as well minimalistic with blight flashes emerging all the time. The whole performance is meant to be a play with contrasts. So, something has to be changed for sure to make it more memorable for the audience. Memorable in a good way, of cause.
