The people of our society need to be careful about believing what we hear from television. The biggest problem with this movie is that America was so gullible as to believe that such a serial killer exists. Think about it for a couple of minutes. How come we have all heard of "Jack the Ripper" who claimed less than 20 victims, but not of this "Gustavus", claiming more than 300? Think a little bit harder. Yes, the trailer to this movie is misleading, but they never outright said that it was a human killer, only explained it in such a way that we might come to that understanding. This movie's "Twist" if you might call it that, was probably the worst since M. Night Shyamalan's- The Village, but any means of a large income for writers, directors, actors, etc. will always be taken in Hollywood. Always be suspicious. Think about all the swamp and water scenes of this movie from the preview. The goal of many infamous writers and producers is just to make money, taking any chance they are offered. They want quick revenue wheter or not America is satisfied and by harshly misleading citizens, their ticket revenues skyrocket. Investigate a little bit, you should never expect more from Hollywood.
