A movie about real life teen hero who is risking her life to save school mates in a school shooting. She shows inspiring courage, smartness, perseverance and determination.
She also knows how to shoot which is helpful when the people killing you are using automatic weapons.
The movie also address the issue of personal responsibility and rejects the lame excuses that our politically correct society uses to blame school shooting and every other crime on bad childhood, inattentive teachers and society.
No wonder the liberals on rotten tomatoes, who can't stand heros, and people who can fight and shoot to save lives and hate personal responsibility, are giving low rating to a great movie. Well worth watching
