I really like the look of liquid glass, but especially on macOS. It really makes me feel like going back in time, it reminds me of messing around with Compiz and Beryl on Linux. Making stuff look as glassy as possible, and it really fits well on my 2006 iMac-turned-display.
But where is the liquid glass? Just the dock, menubar, and widgets?
I would be glad to see some depth and texture come back to the UI. It should be more than just a few background elements, because as it is right now it looks inconsistent. It would have been better if they put more focus into the chrome to make it less stark. The dock and menu bar were already somewhat transparent and blurred, which is good.
Until something is done about the flatness, dark mode is a necessity just as much as a preference.
