I think it's fine. Is it a bad song? No not all all. Is it a winning song? Definitely not but it's decent, safe and rather current considering. I thought there were three 'safe' choices for mid table mediocrity, but this has grown on me a lot since last night.
Obviously it's quite hard to say they're going to be bad performers because of how dreadful the stage was on top of the camera work but I do think there's some potential there, and the guys seem pretty enthusiastic and capable live singers. Let's see if the BBC have realised that a tightly worked live performance is vital. I think the two drummers works, and a lightshow in the style of Finland 2014, but then I'm sure the BBC could find a way to ruin it with poor, static camera work.
