Haven't followed the German NF too closely, but looking over the performances, I can't really complain about the winner. It's a fairly standard midtempo piano ballad, but it's executed well, and that at least puts it a good sight above Perfect Life for me (and probably Ghost too, especially if you're comparing live performances).
On a personal level, I probably would've preferred Voxxclub - who brought something with real character, a fun stage act, and native language - but Michael was a close second, and as far as Germany's goal of hitting the top 10 goes, Michael does seem like their safest option. I'm guessing it'll get the country its best result since Standing Still in 2012.
For now, I'll give it 6 points, though that could either grow with time or fall off if the song starts to irritate me. Both are possible.
