I just posted a review, but It didn't work. Excuse my poor english by the way.
First: great acting. Earle Haley doesn't play Rorschach? He IS Rorschach! Wilson was quite good in his nite owl part.
soundtrack: Bates did a great job. But it's the old soing's choice which is great, and stay true to the choice Moore made. From dylan to Hendrix, it all fits perfectly to the story.
Action: very violent, lot of blood. nice choreography, in a hong kong style. Well shot and well cut, Snyder did his bet shot so far.
story: great characterisation.
best scene: Kovacs becoming Rorschach.... incredible. As much powerful as in the GN!!!
changes: some are minor (silk spectre's origins...) and work perfectly. concerning the giant squid: its repalcement works. its a clever way to deal with this situation and it stays true to the GN's spirit.
My only real complaint is about the scene in which we see all the dead in the GN, with a lot of blood. It's kind of disturbing, and makes the ending unforgettable. In the movie, we only get to see a crater, and it's not as powerful. So disappointing!
Anyway, a great adaptation. I can't wait to see the director'scut!
