The movie was slow as hell to start but got there in the end. It is very much like the inquisitor episode of Babylon 5. It also have elements of The Cube, 2001 A Space odyssey, THX 1138 and the Terminator. All of it wrapped up in 1 man in a room alone. The best thing is the ending makes you think that he may not have actually escaped at all and is still in the cell. I liked it.
