What a massive disappointment.
I'm a huge fan of the original GN (hell, I even have the first run original issues of the series).
I felt like there was no imagination brought to this translation. Yes it was faithful, but some stuff just doesn't translate. Many, many plot points that should have packed emotional punch-- Silk Specter / Comedian revelation, the realization that Ozymandias is going to destroy multiple cities, Comedian shooting the woman he impregnated in Viet Nam, etc. just fizzled here.
For me, the best parts involved Dr. Manhattan, especially his origin, though I would have liked a few more moments of the brain/ nervous system walking around. Jackie Earle Haley was perfect and I also like Patrick Wilson's Nite-Owl
. And yes, like everyone else, I loved the opening credits.
In seeing Watchmen on screen there are a few things that I realized about the GN -- Rorschach is a truly tragic character; his last moments when he realizes everything he's ever done has been for nothing were the most moving of the whole film, imo and Silk Specter is not a terribly well-developed character in the comic to begin with.
Over all, I think Snyder wanted it both ways. He wanted to please the hardcore fans but also make a very traditional super hero blockbuster and in doing so, he ended up with a mushy, non-impactful middle of the road piece of work. It's a shame because if the structure had been fixed, more character work had replaced some of the sex and violence and the godawful abuse of pop music was left out this could have been a very strong film. Ah well.
