My problems with Watchmen stem more from Miller in general. The man gave the comic industry a shot in the arm, but I think the success of Miller's initial work tainted the medium.
Superheroics are supposed to be escapist fantasy. A world that is simpler, easier to define. When I was growing up, those stories bored me to tears and I wanted drama and action and heroes that weren't afraid to get their hands dirty if they needed to. I saw no problem with Batman killing Joker's henchmen or shoving a stick of dynamite down a lackey's pants and smiling as they died.
As I've gotten older, my knowledge of the world around me has broadened and then I turn to Comics to escape the day to day grind only to find the characters I grew up with there dealing with much the same - even worse situations.
My three favorite heroes growing up were Darkhawk, Iron Man, and The Green Goblin (Phil Urich). Yeah, I was a Marvel guy.
Darkhawk was a long time backburner hero who was unceremoniously killed and the source of his powers utterly destroyed after being corrupted by an evil force.
Phil Urich - the Heroic Green Goblin - was transformed into a raving psychopath and the new Hobgoblin
And Iron Man...well. I could rattle on about Tony Stark's descent into character assassination that Marvel could only cure via explosive amnesia, but for me his end came much earlier then that. In a "Christmas" issue where New York is threatened by a Terrorist plot (This was circa 2001 or 2002) to detonate a nuclear device delivered via submarine.
Iron Man catches wind of the plot and proceeds to ram into the Sub...while it is submerged. We get a two page spread of Iron Man erupting through several bulkheads of the sub, with water filling in behind him as terrified crew only begin to comprehend their destruction. Iron Man then attempts to disarm the nuke (Coincidentally, he did this with ease back in the Early 90s when he fought the Military Armor gone Rogue Firepower), but cannot and is at the end of the issue saved by a literal Angel (Not the X-Man, the Heavenly Host variety).
So yeah. Given how prior to this, the taking of a life was something Tony Stark was fundamentally unwilling to do (and something which destroyed him in the few cases it did happen), watching him brazenly sentence an entire ship of people to die only to be delivered from death itself by literal Divine Intervention...
So yeah. Needless to say, I'm not a fan of Miller's legacy or what his work being used as the announcement for this Batman/Superman film might entail. All I will say is I am seriously considering picking up Golden and Silver Age trades...because the Modern Comic Scene has no merit to me any longer. I don't want to watch imperfect people make the best of a series of bad choices or be like "real people if they put on the mask".
I want my icons, ideals, and role models. The reason I adored Captain America is because he was the ideal. Steve Rogers was not "darkened", he was his Golden Age Persona through and through, and I loved it. It gave me hope for Super Heroes again. That it doesn't have to be about the Kick-Asses and Watchmen, there is room for hope for a better tomorrow, that men of good character still do exist and are still given over by fate to great purpose and deeds.
I miss the age of Heroes.
