I didn't understand this film one little bit. Plenty of blowing up and killings, running around and shootings. I love Gerrad Butler, he can be a great actor and done some great films too, very easy on the eye, but he hardly says 2 words in this film and runs around shooting folk in some computer generated game. If i was to tell someone what this film was about, i would say its on the lines of Running man vs Surrogate (the new one with Willis where people live their lives view computer generated androids) some sort of computer generated game for survival. Thats it i don't get anything else from it am afraid. But it was sort of watchable. The best bit? Marilyn Manson singing 'sweet Dreams' for the sound track of course!
