R-Rated Movies

Has anyone ever seen the first King Kong movie? The black and white film made in the 1930's? Would you believe me if I told you that, back in the day, when people first saw this film, they were terrified of this giant gorrilla? When people look at the film these days, they see a stuffed animal hobbling around on the screen. What's my point? People are growing up quickly and are becoming accustomed to new technology and special effects that are used to try and scare us.
What's really my point: The age to see an R-rated movie should be lowered.
What is it that bans teens under the age of seventeen from seeing an R-rated movie? It's nudity, violence, gore, strong language, and a few other things.
But what stops teens from seeing these things in everyday life?
There is one big source for all teens who are curious about any of these. It's called the internet. Yes, your parents may blocked you from some web pages but teens are smarter than that. They have friends, some may be older, who, with some persuasion, can get them what they want. It's not a difficult task.
I believe that 16 is a good age to see R-rated movies. If they choose to go, it is their decision on what they want to see.
Do you agree?
