i like the fight scene however some part of the movie just doesnt make sense.. Even people don’t know the hand sign, how can they cannot read that woman body gesture? Just because you holding knife, it does not means that she is a bad people. Some use to protect themselve from ‘something’. She totally looks like terrified of something and asking for help. How can no one couldn't read that? And then, what’s the function of that alarm if no one coming? And I kinda frust the way that psycho die..
