Blocking the artwork in with silly dividers ruins its impact. All that clutter distracts from what could have been a memorable poster. And who needs the quotes?
This design (as well as the others in this group of posters) is based on Dave Gibbons'(and Alan Moore's) original promo posters for the graphic series.
As such, they reflect the comic origins of the series with its framed structure and text sections.
Isn't done like that on purpose to be as close as possible to the original comic ads which had that exact layout. I thought that was the point and therefore what made it cool, authentic and not like everything else.
