Having read good reviews if this movie I was very disappointed that it did not live up to my expectations. The acting is simply awful - at times wooden and other times cheesy. At the point when the main characters discover their alternate dimension alter egos their reactions were that of two people that had just discovered a new TV box set, not just witnessed something totally unbelievable and shocking. From then on it just got worse as the plot just became a predicable goodies versus badies plot. No explanation at all as to the motives of the alter egos. At one point in the film I wondered if I had missed the fact this movie was a spoof and not an actual thriller! Really don't bother with this poorly thought through and badly acted nonsense!
