M. Night Shyamalan's Trap has a high school level notion of psychology
Shyamalan never graduated to mature themes, didn't he?
Trap has a high school level understanding of psychology. The "profiler" is laughably an improbable individual who can precisely detect the exact behavior of an unidentified person in a concert event.
It cracks me up when the profiler would say something like "he's already running out of options" without having identified the murderer.
It was just too plain stupid.
