I'm with you both, CrimsonMist and Agentsands77. And that's an awesome sounding scene, CM. Who knows, though? We may very well get something like that. But the idea of a familiar looking world with something totally supernatural just casually existing within it--that's cool. That's how I've always imagined Watchmen as well.
I have a feeling Snyder has a few things up his sleeve. We've barely seen anything, and we know how devoted he is to the source material. I think he's attempting to do the movie equivalent to the comic, not so much in slavishly adhering to the source material frame-to-frame--but more in taking the allegory in the sense that he's doing a "send-up" of the comic book movie. Expect some gloss here and there, and a few cliche's thrown in.
I'm just crossing my fingers he doesn't get too deep into parody territory!
Well, it kind of goes both ways, and i hope Snyder finds a way to balance it. The thing about Watchmen is that it takes you down the familiar streets of New York City, and slowly begins to alter everything. The first thing noticed would be cars, then the poster to re-elect Nixon, then maybe the cigarettes. And then you realize that this New York City isn't the same New York City that your familiar with.
I think it's very important to capture that on screen. Familiarize the viewer with what they've seen both in real life and in, say, Spider-Man(being as how this is a comic book film). It would also be a commentary on films like Batman Begins and The Dark Knight(be it intentionally or unintentionally): Superheroes in real life? Ridiculous! But that's what Watchmen is isn't it? The preposterousness of superheroes in a world that more or less reflects our own.
On the flipside of that, it's also important to make a commentary on past cinematic superhero films, as Snyder's stated many times. Naturally, Snyder's doing that with the costumes of certain characters, and Snyder's also said that his "Batman" (Niteowl) can't get it up, "Superman"(Doc Manhattan) doesn't care about humanity and the "bad guy"(Viedt) wants world peace. That should get across, and i'm hopeful that these references will be seen by general audiences. The stylization though, may cause problems. The stylization seen in the film may be a commentary on how stylized all these past superhero films are. Fans might get it, but the general audience might not. They might just see it as another stylized comic film. But it all goes back to setting it in the real world as best as possible.
Snyder may very well have something up his sleeves, and i'm hoping he does. Cliches HAVE to be in this movie. I think it's all essential to the build up to the ending, when genre convention is thrown out the window. That will be a magical moment, indeed.
and thanks for the comment, regarding my "fictional" Vietnam sequence.
