I was a huge fan of Chameleon and it was in my top 3 over all... Although this song is quite different I think I feel about the same about it! Maybe I like it a little less (my top 5?), but it is more contemporary (so would imagine more wide appeal)...
Apparently not? Eurovision fans confuse me. In the UK there is often a lot of moaning "why can't we send something that would easily be in the chart top 40"... Every song has echoes of another... With this it's Beyoncé "Running" and Emeli Sandé "Heaven"... Both great songs so surely not a bad thing! I can easily image WOW in the UK top 40 sung by Katy B, Emeli Sandé or Jess Glynn... It's like you can't win no matter what you do...
In other thoughts it caught me first listen, and grows from there. I think a good presentation would make this really stand out. I also think this will be easier to sing live, the effects are on the track not the vocals.
For me, Malta have just replaced a really good entry with another really good entry, and I don't get the hate for either... Both WOW or Chameleon would be worthy winners in my mind.
