R-Card and Smoking

ABC News is reporting that GKC theaters which is in 24 cities is going to allow kids to attend R-rated films without parents as long as they have an R-card. What's an R-card? It's a card that the parents have signed that says the kids can see an R-rated film. It's 2 dollars but should kids be allowed to see R-rated films at all? Shouldn't parents have to do things to help their kids learn? After a kid watches a movie like The Passion of the Christ shouldn't the parents explain it all and help them understand. Can kids understand the content of many R-rated? Let me know.
