During the 90s, people argued that teens watching movies like The Texas Chain Saw Massacre would get a twisted notion of what normal was. The detrimental effect on teens was seen as such large that they banned the cartoon darkwin duck for TV, and blamed TV violence for the increase in violent crime amongst youths.

Those claims has since proven at best to be speculative, at worse outright media fabrication. Studies have shown that even very young kids can distinguish that what happens on a movie is not real, and that the social rules that gets shown on a movie does not exist in real life. Teens and adults has a more mature brain and longer life experience that if there was an effect, movies would have destroyed them long before.
