Never needed banning.
I have let my kids watch violent movies from day1 (hear that whine, thats the social services black helicopter starting up), they dont care about the violence in them, and they are have not grown up into violent thugs - proof of the pudding etc that violent films do not make violent children, one is currently on a course, 2nd is in a desk job in admin, third is studying for exams, 4th is top of his maths class, 5th is into dora the explorer
The only people who seem to say that letting children watch violent films makes them violent are
1) papers / politicians
2) do gooders/social services with a job to keep
3) Parents of violent children who have brought up little monsters and want to blame anything other than themselves for their crap parenting creating said monster. (yes, you with kids that are hanging out on street corners in groups)
Posting anonymously so the nspcc dont steal my violent film collection, rocky has a good story I tell you!!!!!!!!!
