a) it’s not an obvious attempt to make it “relevant”: it takes a better writer to avoid being obvious
Whereas stuff like peopel spraypainting "Who watches the watchmen" everywhere is oh-so-subtle.
Alan Moore tends to be incredibly obvious and transparent with his key themes. I can provide examples if you wish. WATCHMEN is no exception.
So...the obvious element that already exists in the book is not allowed to continue to be obvious? Yeah, that makes sense.
I guess we should have Jon say "She thinks I am...not human now...like something greater than human..."
Can't have him say the obvious, now.
So, it's not ok for the Manhattan element to be obvious (even though it already is) as opposed to the squid not really even, on its own, being relevant to "quis custodiet ipsos custodes" at all. Unless you count the random squid eye image...which, let's face it, isn't half as clever as the elements the Manhattan plot brings to the table, where a trusted watchmen now turns to an object of fear.
Thematic elements.
A picture of an eye.
Thematic elements.
A picture of an eye.
Hmm...
This is really your argument?
b) it collects in one single image the whole distortion produced by vigilante in that fictional world;
So does Dr. Manhattan's attack. That image is "Rogue Dr. Manhattan".
I know, I know, we won't get giant tentacles.
Alas.
c) as a metaphor, it applies in many senses to the characters (many of these I’ve already discussed here, and at lenght);
Oh, thrill us again with the metaphorical significance you personally have found that you simply cannot prove was ever meant to be there.
The monster is metaphorically significant because it means "Monster?"
Wow, that's clever Mercurius.
The monster is significant because it's Veidt's monster side surfacing?
But wait...I thought you said being obvious was a bad thing.
Seems to be that showing Veidt do evil things to illustrate his "monster" element (which may have never been intended, but is cool nontheless) is a lot less obvious than dropping a tangible monster in New York City to do so.
And don't you like things that are less obvious?
d) it doesn’t mess up with the whole story; also, it doesn’t stress fear, but the collaboration;
Using Dr. Manhattan doesn't mess up the whole story.
Collaboration?
Tell me Mercurius, do you think, logically, that the world bands together because they've suddenly discovered they have no differences?
Or because they FEAR THE ALIEN SQUIDS WITH BEE REFLEXES THAT MAY ANNIHILATE THEM ALL?
Hmm...
e) it fills the same idea of “abuse”, ‘cause Veidt not only lies, puts the other heroes out of reach, and drives the two most powerful countries to the brinks of war, but also disposes of every single one in that plot, including the whole bunch of scientists, artists, writers, etc. to that bizarre last effect, which is the crown jewel of abuse
So does the movie story and plot. On essentially the same level. Keep reaching.
f) it has a reaaally big eye, if you’re so worried with Juvenal’s verse “quis custodiet ipsos custodes”.
So..."squid watches the watchmen"?
g) and more: doesn’t make Veidt an idiot with “mad bomber tactics”.
As opposed to "mad squid bomber tactics"?
How does using lightning instead of the squid inherently make him an idiot?
