I'm astonished that some people are rating this movie a 9 or 10. It really just isn't that good. Sadly, it had all the tools to be successful, including an interesting premise, a wealth of experienced acting talent, a great filming location, and convincing effects (although this being 2008 you can't really give much credit for the latter anymore).<br /><br />Unfortunately, they still managed to screw it up. The villains' actions didn't make much sense, neither did the protagonists', for that matter. They consistently made really stupid decisions, presumably to create tension and a "stalking killers" feel, except the killers weren't scary. The "twist" was predictable and lame. Dialog was passable, but nothing to write home about. I did feel the actors all delivered the best performance they could with what they had, but there just wasn't much to work with.<br /><br />The script really needed a couple of critical rewrites before going into production, I actually laughed out loud at the cliché "dramatic face painting in preparation for war" scene near the end. The ending is frankly boring and unsatisfying. Instead of this movie, you could just watch Mad Max and Doomsday while completely hammered, then take the resulting mess of memories and remove anything entertaining or intriguing, it will be the same experience but far more fun.
