Kind of pressed for time here, but it’s the fine details of a comic like Watchmen–not the generalized story–that push it over the edge from good to great. Yeah, Alan Moore scores points for fleshing out the characters to a degree that you typically don’t see in the superhero genre, but it’s the book within a book, the repeated symbols tucked away in the backgrounds, the supplemental pieces and so on that complete the experience. These are things that can’t be reproduced on film the way they are in the comic.
If you want to draw a Shakespeare analogy (and, mind you, I’m no huge fan of the Bard, but I’ve read the greatest hits), I would say that all the finery of Watchmen that I’ve just mentioned is analogous to the language of Shakespeare. Whatever can be said about his source material, the language is uniquely his, and that’s what makes his plays as memorable as they are. The bulk of his material obviously has its own merit. Can you really say that about a film genre that’s choked with Daredevils, Ghost Riders, and Cat Women?
I’ve seen a fair number of the current generation of comic book movies, and while some of them are genuinely good (The Dark Knight, Ghost World), I have yet to see one that genuinely does the material better than it’s been done or could be done in comics. Partly, it’s due to the filmmakers not fully understanding what it is that makes the material good (cough cough Wachowskis cough), but a big part of it is the simple fact that comics are not movies. Unfortunately, the more people patronize filmic adaptations of comics, the less incentive comics will have to step out of the hunched-over and decrepit shadow of film.
And just to be absolutely clear, as I’ve said before, what I want is not to have existing comic book movies taken away. I just want them to stop being made.
