When I went to Blockbusters for my 'Five for £5' deal this was the only Horror Film I could find on the shelf that I haven't seen. After watching the trailer I had low expectations of this twisted tale of tequila fueled young people seemingly hunted down by... an ancient Mayan Temple. Low expectations indeed. The film delivers on all fronts and has genuinely queasy body 'invasion' moments. Sympathy for the victims emerge when you realise there is no way out from the scenario, even when they do what you think they should do if it was you caught in the same situation. Digging a bit deeper into the history of the film, it comes from a 'Best Seller' Novel, Dreamworks and Ben Stiller... see what the horror hides.
