Aesthetically, the start screen and charms bar are only out of place because of left-over inconsistent aesthetics on the desktop that haven't been updated to the flat look yet.
Ergonomically, I really don't see any problem - the charms bar is never used on the desktop, you should be typing on the start screen if you have a keyboard connected.
Leftover bling and non-updated icons is a problem, this has been a problem with every version of Windows, I wish MS would fix it.
I think there isn't enough settings duplication. As it stands certain things are only available in the Metro settings and certain things are only available in the control panel. I'd prefer every setting that affects non-Metro to be available in the control panel, every setting that affects Metro to be in the Metro settings, and every setting that affects both to be in both settings locations.
I don't have a problem with the shutdown location, on any hardware than can run Windows 8, you can just push the hardware power button to shutdown.
Not really sure what you mean by settings layout and hierarchy.
I quite like Windows font rendering - I prefer it to Mac OS at low DPI settings, haven't gotten around to trying Windows on any of my hidpi displays. Not sure what you mean by inconsistent rendering.
They spent about a decade failing at that. Unity is pretty much the only comparable thing (in use case, not in implementation) and we've still got about a year before Apple throws their hat in the ring.
As far as I can tell what has most people (not you) up in arms is sensationalist media, an inability to think critically and a detachment from reality.

Make something that works on different form factors, without totally redesigning the familiar desktop
