I agree and refilled my position yesterday, and finally got to see the movie. I am totally bored with special effects movies but C&A's were excellent and worked well I thought. I never saw the Graphic Novel but imagine the movie followed the story board and perhaps too much so.
They edited the beginning severely I think as it didn't flow well at first. They could have called it Cowboys, Indians and Aliens. That cracked me up when the Indians showed up.
Considering this was to be done 10 years ago and finally came to life its quite a tribute to management.
Serendipity is the effect by which one accidentally discovers something fortunate, especially while looking for something entirely unrelated.
