The performance lacks a connection between artists and the camera, and that is probably one of the most important things for Eurovision. They are performing not for the audience in the hall, and not for their fans, but for the millions of viewers who see the act for the first time in their life.
And for the first time viewer the backdrop may seem to be impressive, but the band is too static on the stage and lacks eye contact with the camera. Perhaps, they are not yet too comfortable with the stage.
The song is still the winning material but the staging needs to be improved to connect with the audience.
