So I saw Watchmen at the midnight release and I that I am the far opposite of the target market. I've read the book a dozen times (official count) and I am a director myself. I went in with an exact vision of what I wanted the movie to be. I was shocked, not at what was taken out, but what was added. Director Zack Snyder added more sex and violence than I ever would have predicted. Of course, all is not lost.
As I said, I am not the target audience. The movie does something very right. More than anything it begs viewers to read the book. A queue has already formed for all my friends who want my ragged old copy. I've been trying for years to get my friends to read it. In this, Zach Snyder did what I never could.
