I have to agree there, the ending made a lot more sense in the film.
The original ending would have probably required the exposition of the whole parallel sub-plot of the pirate ship, and the missing scientists, writer, and artists in the creation of the cthulu thing. Probably about 45 minutes if you didn't want it to seem completely random. Maybe less. I'm no filmmaker. I liked that you saw the paper-man and the kid reading the comic in the scene of the explosion. The film was more poetic, in many ways. I do, however, love the way Doc Manhattan's chapter in the book is set out.
And Jitterbug, I think V for Vendetta is a good movie, but not a great adaptation. If you know what I mean. Stephen Fry's character was good, and very concisely brought the vaudeville element, and showed us the public view of the government as we could guage their reaction to his show - something which I think would have taken a lot of dialogue from bit-players otherwise. Obviously the scene where the girl dressed as V is killed also gives us the climatic "Moral event horizon" for the general public and thus sparks off the third act. I also think in movie terms it was wise not to blow parliament at the start.
Anyway, back to Watchmen, does anyone else find the level of fan worship for Rorschach to be slightly alarming? In terms of the real-life vigilantes on the DVD extras who say they "are" Rorschach and the like? While his conviction to the truth is laudable, his moral compass is all over the place.
Strangers on this road we are on...
