I don't believe that if an individual were to see someone kill on TV it would have motivated him to kill as well, unless there was something very wrong with him or her in the first place. One problem that I encountered in dealing with television is that when I turn on the TV I might see something violent that I do not wish to see. Later, I find myself unable to sleep with my imagination running wild. Also, the system of rating should be improved. Further, I believe that the violence that we see in films is often unnecessary.
Action films can exist without as much violence.
Action does not mean violence. The problem is that the companies which are producing these films, produce what sells and we are paying for all this violence. I believe that the movies we pay to see are a reflection of our society, not the other way around. If no one went to see violent movies, there wouldn't be any, or at least there would be considerably fewer. The media is an easy source to blame, but we are the ones glued to television screens watching violent films.
