Age Restrictions

ehh i think the movie ratings are ohh k only for movies like house of a thousand corpses, if a 9 year old were to see that he/she would fucking have nightmares for LIFE and i can just rent it, but rated r is gay, all it shows is a little nudity and a little violence, listen, a kid knows that if he goes to see a freddyv jason he should know about the damn movie in the first place, My friend has 2 parents that keep him constricted, no rated r movies, and NO rated m games... Damn he hates it!!! And i dont like the fact you have to be 18 to buy rated r movies, i mean i understand pornos and shit but... I just wana fuckin buy some tickets to the underworld with some chicks damn man why do i have to ask my brother or mom for that? Jease.
