For those who have read the book this movie is an epic, must-see event. For those who have not read the book I imagine there a few places in the movie that don't make sense. The movie doesn't spend much time explaining the Keene act, glosses over the police strike with almost no explanation, and Bubastis' role is cut down to a cameo with no explanation of what s/he is.
There are a few points where either the acting was a little flat, or the dialogue was just too 'out there' to feel natural. Billy Crudup and Carla Gugino both had scenes that felt this way.
Jackie Earle Haley's portrayal of Rorschach was dead-on. Hope he gets an Oscar-nod for this one.
I found this movie to be sufficiently entertaining while being extremely informative. The movie begins by focusing on university professors and a member of the Smithsonian Science dept who are all fired or let go for either working on Intelligent Design, or in one case a professor was let go because she just acknowledged the existence of the theory of Intelligent Design in her class. The movie then moves on to discuss that there are many flaws within Darwinism and how nobody within the scientific establishment will allow any sort of scholarly discussion or debate between Darwinism and Intelligent Design. After that Ben goes on to discuss how Darwinism was the foundation for the philosophy behind the holocaust. He even visits a couple holocaust sites. This movie is not the most entertaining film I've seen, but the message is very important and I encourage you to see it.
