If you have made it already to Mexico then there are no spoilers. The film has been made out of re-editing the games cut scenes and dropping some game play in here and there. This is a bit less than i expected and nothing more than what a fan could do with a copy of the game and Windows Movie Maker.. But if you have a spare 1/2hr and are a fan of the game, enjoy.
