Simply Amazing
The true point of this film, ending and all, is very deep and frightning. Do most of you remember high school? Were you ever picked on? Let's use this as a prime example. People want you to conform to how they are, when in fact they are conformed to rules and standards in life, making them brainless "robots" if you will.
Just because you aren't a jock/prep/christian/brainiac/popular, doesn't mean that you are alone. You are unique, and a thinkiner, you have your own mind and don't follow rules.
The ending, btw, just proves how the afore mentioned can just continue on with their lives as if nothing happened, making them truly cold and evil.
