Movie Ratings

Alright, so I know I'm way behind the times, but I just watched This Film Is Not Yet Rated and wow. There was this one guy, and no I can't remember who it was because my memory is God-awful, but he said the most intelligent thing ever. He said that if you make a movie and you show tons of people getting shot and killed but you don't show the blood, then it's fine and it will get like PG or PG-13. If, however, you show people getting shot and then show blood and guts, then you get at least an R rating. Well, he suggested that it should be the exact opposite. If kids today are to realize that violence is bad, then they need to see the consequences of violence. If every time someone is beaten, stabbed, or shot in a movie and they show the real consequences and gore and just plain nastiness that comes from it then they'll really understand violence and it should be those films who never show what happened after that guy got shot that should be restricted from view. 

How simple and how smart is that?
