I agree it appears intentional. A reply on Twitter says it looks like they intend a stylized 50s look/feel, and that’s definitely plausible to me.

Granted I don’t watch a lot of movies, but the production quality of TV I watch has improved by leaps and bounds over the last couple decades and continues to do. I don’t know if that automatically extrapolates to movies but I’d be shocked if they’ve had such sharply different trajectories. If anything, I was expecting this to be some kind of an uncanny valley sort of complaint… not a pretty obvious creative choice.

It seems like what keeps getting worse as the technology improves is the pervasive, uncharitable hot takes.

Yeah, this looks like a very deliberate effect to me. I don't think I'm a fan of it, but this isn't what trying and failing to blend the background and foreground looks like.
