What's good about these pictures? If you released them on Instagram on an anonymous account, nobody would give a shit.
You're right, if you post these anonymously to IG, no one would bat an eye. But it's published in a prominent fashion magazine, it's taken by the famous Juregen Teller, it features celebrities posing in an unflattering way, they're wearing the latest designer clothes, and it got a ton of negative attention on Twitter and other social media (all attention is good attention).
A typical amateur won't be able to do that (they probably think they can). I consider his style to be real and "amateurish" in a deliberate way. In some ways, I feel he's parodying amateur photos and putting famous celebrities in situations that normal pros don't usually would or can. Here is another site that tries to describe it: https://www.highsnobiety.com/p/juergen-teller-w-magazine/
I'm also not one to critique photos from a technical perspective, and tend to go by feel in my own and others photos.
When I was more serious into photography back in the day, getting a photo that can express what I wanted it to feel or the story I wanted to convey was much harder.
