Dispatches from the Fraying Edge

Am watching the latest restoration of Fritz Lang's master opus Metropolis. Just saw the scene where the hero (such as he is) goes underground for the first time and sees an explosion that claims the life of some of the worker drones.

The scene reminded me of Part II of Ginsbureg's Howl (The Molech section) and especially of this passage:

Moloch whose mind is pure machinery! Moloch whose
blood is running money! Moloch whose fingers
are ten armies! Moloch whose breast is a canni-
bal dynamo! Moloch whose ear is a smoking
tomb!

Is there a term for something that is dystopian and utopian at the same time? Would that be the definition of a paradox; are these two concepts opposite pole of a binary or are they on a continuum of sorts?

A Little Something Extra:
Without looking it up, do you know what the connection is between Metropolis and one of the most successful film franchises of all time?
