Incredibly dull, lazily written and produced song. Starting with the vocals. Technically okay, but the same over-polished emotionless style French-speaking countries seem to obsess over. Clothes, horrible. Staging reminds me of "Sugar" from 2021, which is not good. Come to think of it, that also had long high notes at the end. Then, the song.
YIKES, what a mess of overplayed cliches. The backing sounds like a 90s auto accompaniement keyboard, and everything just embodies the worst of lazily written 80s Eurovision bottom-feeders nobody wants to remember. Asides from the adequate soulless vocals, it just sounds amateurish all the way through.
This looks likely to be their first NQ. To save it they would need to change the arrangement entirely, make it much more modern, dynamic and punchy, possibly change some of the vocal stylings, and of course change the staging as well. It won't be a masterpiece anyway but, god, really.... Luxembourg is already shaping up to be a "filler country" in the contest. You can do better.
