I'll say this on Clock. It's last two issues are great. The problem comes from the ten previous ones, because Jonhs tried to do far too much, adding far too many players, when the core cast of Watchmen was extremely tight and the plot extremely simple, but thus extremely powerful. Doomsday Clock meander far too much, by mixing the Watchmen and larger DCU together, with new characters who serve next to no purpose (Mime and Marionette, Rorsarch II), returning characters who shouldn't have been brought back (Comedian) and a large misuse of the DCu characters, with far too many cameos.
In fact, I'll go as far as saying that the Supermen Theory and the metahuman arm-race would make for an incredible series, because of the various geopolitcal elements it could lean into. But it'd require a lot of constant research and writers/artists/inputs from people of those countries.
I think my problem is that until issue 11, Doomsday Clock can't even decide what is its plot.
