text: I watched this film not knowing anything about it. I had presumed it was a sci-fi b movie of some sort. How wrong I was. The plot is enthralling and intelligent, the cast are all charismatic and the whole film just makes you think for a change. Some of the riddles stumped me completely but in the end the answers were rather simple. I am quite baffled at the low scoring of this film as I thought it was quite unusual. If you liked the film Se7en (Seven) with Brad Pit or The Matrix then you will like this. There is no major special effects or fancy gimmickry here at all. It is all about the plot, about building the characters and building an atmosphere. It is a film however than ultimately provides no answers which may irk some people but I thought the ending was great. I am still not sure if the film is based on an true story or not.......
