If Will Eisner made comic books an acceptable artform, Frank Miller is the creator who made them accessible to the masses. Movies adapted from his comics in the early years of the millennium (Sin City, but more importantly 300) proved there was real value, not only visually but in the storytelling. And yet, his reputation, wide as it was at that point, has begun to shrink around a single work, The Dark Knight Returns. Is it his best work? How about I make a case for Elektra Lives Again instead.
Miller's Daredevil was a naked predecessor to his Batman. He actually spent more time with Daredevil than the Dark Knight. They ended up crystalizing around Matt Murdock's relationship with the assassin Elektra. In recent years Batman's relationship with Catwoman has danced around similar ground, but where Batman's greatest loss was the death of the second Robin, Jason Todd, Daredevil's was Elektra's. As with many comic book deaths (hey! even Jason Todd!), Elektra's wouldn't be exactly permanent.
But Elektra Lives Again might best be understood as a fever dream.
Or a series of them. Daredevil keeps having tormenting dreams about Elektra's corpse being violated, the ninja clan she once ran with refusing to let her even rest in peace, for having dared reject them for another life. Eventually it seems as if it's really happening. It probably isn't. It doesn't really matter if it is. The point remains that this is a superhero story about a man in immense pain.
After Miller transitioned to writing Sin City comics for Dark Horse, Jeph Loeb came along, and along with Tim Sale ended up writing comics like Batman: The Long Halloween, which tapped into the vein Miller had explored with Batman: Year One. Loeb and Sale's partnership eventually migrated to Marvel, where they proceeded to create character studies for several of the company's best-known characters (Daredevil was, of course, among them).
Now, comics have done a lot of things over the years, but character studies are still fairly rare. Miller's work was among the earliest. These are stories that are less concerned with traditional superhero action (although that can happen in these tales, too) than the face behind the mask. Watchmen still remains the most famous of these. In short, while they remain a hard sell at the movies (DC's recent movies), they are still among the most popular and influential comic book material ever published.
Elektra Lives Again is a character study. It's all about Matt Murdock's continued grief over Elektra's death. (It's worth noting that Loeb and Sale's Marvel tales were all written from the perspective of those left behind.) The Daredevil costume barely makes an appearance. It reads, in retrospect, like a preview of Miller's hardboiled noir in Sin City. It's gorgeously illustrated. It goes well beyond what most superhero comics typically do, or have even attempted in the nearly thirty years since it was first published.
Marvel made its reputation by grounding superheroes in pain. No, not necessarily the traditional painful origin story, but what happened along the way, after the origin, when these characters suffered through life, as typified by Spider-Man, just like the rest of us. What sets Elektra Lives Again apart, so strikingly, is that it doesn't pretend that it's easy to reconcile this pain with typical superhero adventuring. Eventually there comes a point (and in contrast to Dark Knight Returns, not even in some distant future encumbered with an aging body) when the pain becomes overwhelming, when it can't just be shaken off. Eventually it results in a Daredevil story without Daredevil, just plain Matt Murdock, and his horrible memories.
So I think this is a pretty important story. A story told with every creative virtue Frank Miller ever had, but one in which he gets to look well beyond the mask, not because the superhero had to move on, but because, if even for a moment, he couldn't.
