I am very concerned about PG-13 movies that have toys marketed to children. It all started when children's comic books or 1980s cartoons were adapted into movies that are rated inappropriate for children.
I believe that one of the reasons for kids wanting to see these movies is because of the toys associated with them. The movies have many toys for children to play with but they only make sense if the children have seen the movie. Kids then want to go to these shows because the toys are cool. These movies expose children to violence and other bad things that they are not yet mature enough to understand.
I believe one of the reasons that we have so much trouble with bullying, swearing, and kids being mean at school is because they see movies that are inappropriate for their age.
On-screen violence teaches children that fighting is okay and promotes aggressiveness. I think companies that market toys from movies should be required to ensure that the movie rating is appropriate for the target age of those toys. Movie makers would make more money because parents would be more likely to take their kids to an age appropriate movie, maybe more than once, and the effect on the kids would be less dramatic. This may also reduce violence and associated behaviors in children.
