Not much to add to the discussion except a couple of personal observations. My wife watched it last night and told me to pay attention to the music. Obviously, she enjoyed the choices and I understand why she enjoyed them. As a Watchmen outsider, the choices were mildly amusing but I could ignore them mostly.
Rorschach's final inkblot made me laugh out loud. I'm fairly certain that was not the director's intention, but I did appreciate the absurdity of it. Of course, I never did understand Rorschach's shifting mask anyway. Perhaps that was a failing of the script.

As the only Watchman without a backstory, Ozymandias seemed the logical villain. I saw through the cyanide pill scene at once.
