Having never read the novel, and going in knowing it was 2 hours and 43 minutes, I was entertained. The pacing was quite good, the character build ups exceptional. Not knowing how the original novel ended, and having an inkling of a notion how the world would react, the 'peace' enjoyed by 1985, does not carry over to our 2009. I liked how graphic it was, very true to comic novel writing, and the real world.
I highly recommend a viewing.
