I heard about this film because I've been a fan of Sharlto Copley since District 9. When I saw the trailer, I was extremely interested. I wanted to watch it to find out why the hell he was in a pit of dead bodies and why he didn't have any memory of how exactly he got in that situation. The plot has many little details that give you hints as to what is going on, but when I finally pieced them together, I was surprised. It keeps you guessing as to whats really going on throughout almost the entire film. I won't ruin the reveal, but I did NOT see it coming. It's a fairly interesting and original film, and I enjoyed the ride.
