They got the character names right but apart from that EVERYTHING else deviated from the book! I was prepared to be disapointed but I was blown away by how far the film deviated from the book. If you've read the original and you are hoping to see it realised in file - STAY AWAY. If you haven't read the book don't let this mediocre bash at sci-fi put you off a great dive in to retro culture and gaming.
