How does the setting of Gotham City influence the 'coolness' of Batman comic book covers?

Gotham City's gothic architecture, perpetual darkness, and menacing atmosphere are integral to Batman's appeal and, by extension, his cover art. When covers effectively capture the moody, rain-slicked streets, towering skyscrapers, and shadowy alleyways of Gotham, it amplifies the overall 'coolness' by immersing the viewer in Batman's world.
