I recommend people read the book as well as see the movie. My understanding is that the movie tries to dramatise what is happening in the book much in the same way that they dramatise the impact of quantum physics on the players in "What The Bleep". I read the book on the strength of the trailer (as I couldn't wait to see the movie). BTW I know this intro is clumsy; I'm about to run out the door at any minute so that the Boi and his friends can have a Buck's night here. I'm basically killing time till people arrive so that the Boi can get some sleep, he worked night shift last night and has not had much rest today.
