...whilst changing the attack at the end, making Dr Manhattan the scapegoat, and killing off Adrian Veidt.
Can't have everything, I guess...
I dont think making Dr Manhattan the scapegoat is such a massive change in the concept and the idea: yes, i would prefer the ending as written by Moore, but I look at it like this:
Comedian discovers a plan by Veidt to bring about World Peace by a hoax attack. realises Hoax attack will kill Billions. has problems dealing with this, leading to his murder. Murder of comedian leads to involvement of other former masked adventurer's.
Its essentially the same thing.Further than that, i think that DocM is ultimatley responsible anyway: he could have stopped Veidt with a thought, and yet he sided with him. think of the Comedians exchange with DocM in Vietnam when he were bottled by the woman and then killed her, in front of DocM
whats important to me, about the end, is 2 things (allowing for the fact that a hoax attak is a must):
1) Veidt must not die. thats paramount. His last exchange with Doc M is highly important:
I did the right thing, didnt I? It all worked out in the end.
suggesting the man the man brought about World Peace never achieves it on a personal level.
In the end? Nothing ends Adrain..Nothing ever ends
the final Panel is the cover of issue one. for me, this is why they should open with, and end with, the smiley face and the stain on it. because it ties directly into that statement, making Watchmen a circular device. If it were up to me, the film would open with that picture, fading to black and then into whatever sequence they open with, and end with a slow zoom onto the pin badge, before fading to black and into the credits.
2)Rorscach must die, at DocM's hands.
Although Veidt is forced to kill millions of people in order to implement his vision of world stability, he is rebuffed by none except Rorschach. The person for whom, more than any other character, the end justifies the means, refuses to accept that this end is justfied by this means. therefore he has to die. Being killed by DocM, and prevented from spilling the beans, is the real signal that DocM accepts what Veidt is doing and wont stop it, which circles back to the point about him being ultimately responsible.
