Honestly, I take it as a good sign when people who think Ghost and Black Smoke were okay, don't like Sister at all. Those entries ended dead last and I disliked them strongly (crazy ninth jumps and butt-focus in Black Smoke, manga girl in laser forest and a boring, monotonous beat in Ghost – spooky, spooky! not. Still salty about Avantasia, Gregorian and Laing).
Sister on the other hand has at least the glockenspiel and the marching, muffled drums going for them, and I remember that the repeated "SISTAH!" on the high C really got stuck in my head when I watched the national selection – and I went into it blindly without listening to the songs prior to the show.
Don't know if people will vote for it, but I'm definitely not as unsatisfied as I was back in 2013, 2015 and 2016. We had a strong national final this year, and it makes me optimistic that I actually like Sister, even though they were only fifth in my ranking out of all the possible entries we could've sent.
