As the comments said before ... this movie was boring. I've bought the DVD on the flea-market for 1,50 and I thought, what can I do wrong? Well, I was proved, that I could have spent the money on something else. The only good part of the movie was when they opened the masks in that fancy house where there was a party. Okay, there's a party ... but from one scene to the other - where the heck are the guests??? Same with the restaurant and the subway-station. ... Talking of subways, when Susana is on that motorcycle and her hands are being taped on it, Toni and Alex are trying to rescue her, 'cause a train is slowly coming closer. Here's the weird part. When they went into the tunnel, it was approximately 100m away from the end of the platform. But when the train chases the motorcycles, it seems like the platform is kilometers away. After watching it, I really regretted it. The idea of the movie was good though, but the result as a whole wasn't good at all.
