Is the NVA a legitimate law?

The video recordings act was introduced and enforced in 1984, after the moral panic introduced by the right wing newspapers. The legislature passes this bill when the Conservative government was in office. The Bill stated that no one should see these video nasties, due to its immoral behaviour. However the moral panic focused on the availability of these video nasties and how easily accessible it was for children to watch them. The act did prevent children from watching video nasties and unregulated films, which made it successful and morally right. However this bill blocked the civil libities and freedoms of an individual over the age of 18 who is more than capable to decide wether or not to watch these films, thus making this  a morally iligitmate law.
