Alright, Watchmen. What else is there to say about it? It's one of the most respected and cherished comics ever made, and deservedly so. It's smart, clever, and a hell of a deconstruction of the idea of the super hero.
However, one thing has always bugged me about it: the ending. No, not the reveal of Ozymandias' plot to unify the world under the banner of an intergalactic invasion/the wrath of Dr. Manhattan; that's a great, morally ambiguous twist. My problem comes with the very, very final scene.
Just to recap: Rorschach suicide by cop'd after learning about Ozy's plan, knowing that he couldn't allow it to proceed, but, at the same time, that it was also the only hope man had left. However, he had been keeping a journal of his investigation, and before embarking to Ozy's Arctic base, he sent it to his favorite right wing newspaper. The ending shows that, desperate for a news story in a utopia without conflict, they may go ahead and publish it. This would, as Dr. Manhattan hinted, lead to the destruction of Ozy's plan.
...Or not. There are a lot of holes in this ending. Seriously, a lot. I'm going to list them all as they come up.
1) They might not even publish it.
The police already had a fake copy of Rorschach's journal, but... only Rorschach knew that, and he's dead. The editor might figure that this journal is the fake and discard it.
2) Who would believe them?
Even if, however, the editor decided to run the story, well... who would give a shit? The newspaper (the name has slipped my mind) is shown as basically being a tabloid, only adhered to by right wing nutjobs (like Rorschach). Meanwhile, Ozymandias is a respected businessman, former superhero, and one of the most renowned men in the world.
Who's side do you think the majority of the public is going to take?
3) Ozymandias has more money than God.
Seriously. Even if they ran this story and people would believe it (that's a huge stretch), what's stopping Ozymandias from buying them out and/or bribing them to stay silent. The dude (according to the film) has enough money to make the Oil Companies his bitch; a small paper in New York should be no problem.
4) How will this story get out?
Getting sidetracked, even if the story is published, well... it's a small company situated in New York. I doubt any major newspaper would pick the story up for the above mentioned reason, so how would anyone else in the country, let alone the world, find out about this? In a world without the internet, it would take a good amount of time for this story to spread, more than enough time for Ozy to silence it.
5) Ozymandias has no qualms with murdering people
Sure, he doesn't like to. But in order to achieve his goal, he killed The Comedian, an island full of psychics, his entire science staff and aids, etc. Not that it's done... why would he stop? If this paper and its staff posed that much of a threat, I think he would despose of them, if there was no other option, in a heartbeat.
6) An investigation would prove nothing
Let's recap: All of the key witnesses are either dead, unwilling to ruin the new, peaceful utopia, or in space trying to create new life. An island and an arctic outpost, both incredibly difficult to find, are the two major locations where this all went down. Both are owned by Ozymandias, who would have had more than enough time to eliminate/tamper with the evidence. The key document pointing to Ozy's guilt was written by a psychopath.
What would an investigation turn up again?
Now, I know you could argue that the point of the ending is that his utopia will inevitably fall, no matter the cause. I see what Moore was going for, but it would've been nice if he used something that didn't fall apart after a little bit of thought.
And please, I'm not insulting the book. Watchmen is a classic, almost perfect piece of literature, which unfortunately the flaws (like this plot point) all the more painful.
