According to the news media, everybody - including DR and Sissal - agrees that the staging must be improved. In my opinion, the most important thing is her outfit, but that hasn't been mentioned so far other than in various comments on social media.
Btw, it's the third time in a row that the jury "overruled" the Danish televoters regarding the winner. My own view on this is that the presence of a jury is okay with regard to appreciating artistic quality, but if the jury's main purpose at a NF is to choose a song they think has the best chance of doing well at Eurovision, then I'm against it. It's a national final, and the format should be loyal to that nation = the viewers.
