I fande the film actually very entertaining and exciting. The plot is up to the end not surprising. There were many typical action elements available, that there was not always everything completely realistic, but belongs to this kind of movie, too little to show. However, I was pissed pushed that the killer has done at the beginning of the film with incredible ease significantly higher than its weight class opponents in the UFC ring, but truly massive hard time against the slightly overweight and untrained police psychologist just before finals. These are points in the film, which would really not have to be. Something can be solved as a writer / director also different.
