I'm not going to rant about it, like I did the hobbit, but just make a couple of observations; firstly, I know why Snyder was accused of being 'in love with the source material', given the number of shots that look like they were lifted straight from the novel. However he seemed to completely miss the point of the book in two ways to my mind: by ramping up the sex and violence but dampening the commentary on it (for instance, the sex scene is heightened and lengthened to a pornographic level, but the 'did the costumes make it good?' dalogue is removed).
Secondly, removing my favourite character arc that highlights the existential angle of the book. It's odd that it's the prison psychiatrist, treating Rorschach, who most makes you empathise with Osterman and his no-frills view of the universe. In the novel, he is deeply involved with rorshach, we see his private life and descent into obsession, and see him come face to face with the meaninglessness of everything. In the film: he spends five minutes with him then walks out in defeat.
Also all the New York street characters were trimmed out, so the ending had no punch.
I'm not going to talk about the ending.
It's just... If you don't think a fake giant psychic space squid is a good way to end a story, why are you going to see a superhero film? Tbh, it does make more sense to have multiple assaults on the earth than just New York, so perhaps that particular aspect of the change is an improvement. But maybe Alan Moore (9% of people know his name, as author of watchmen, the most famous comic ever [source: pointless]) meant it like that. Maybe it's not meant I be a clear cut ending.
So instead going to discuss something else: similarities between watchmen and Sirens of Titan. There's been discussions elsewhere on the net (lmgtfy), but there's a few beats that are similar:
The science accident that turns a person into a being of energy that can see all time and space;
The plot to unify earth by faking an alien invasion;
The flat, deterministic, meaninglessness of life.
What I like is that both stories do something the other doesn't do. Not all of Sirens of Titan is in Watchmen, and vice versa. I like the fact that I know both stories, like both stories, and appreciate the differences and similarities between them. None of that stuff reaches the truth of watchmen, which is all about comics. That's really why it's an unfilmable book, because if you were to adapt it to the screen, you should end up with a film about superhero FILMS. Your reference points become completely different. IT'd be like tarnslating a Russian book into English, that was about the Russian Language itself. Do you keep the references Russian but completely lose their meaning? or translocate the references into analagous English ones? Either way, it's not the same book.
