I thought I was in for a good movie as this started out really well. The way the serial killers plotted out their murders to be a close to perfect crime was a great premise. The cold reality of it reminded me of "Henry: Portrait of a serial killer". Then the movie sinks faster than a rock in a lake. As soon as the detective went into "think like the killers" mode, it got stupid. Then he makes so many bad decisions that don't make sense, which ends up getting more innocent people killed. This movie could have been good, but the writer got in the way with some unplausible stupid ideas. The ending was just as bad and didn't make sense. The big emotional moment in the end was meaningless. This is a good example of how NOT to make a movie. Pure stupidity.
