how can i convince my parents to not let me see r rated films?

All the rating does is tell you there's something in the film the censor has decided is unsuitable for people under 17. But at 21 the choice of what you watch is up to you.

Are you asking your parents to censor films for you & shield you from any that would be R rated? Like asking them to take responsibility for what you watch? Even to stop you watching an R rated film that you started watching of your own choice?

Sounds like they don't understand your reasons. So best to explain to them exactly WHY you don't want to watch them. And why you want them to not let you see them.

yes, PLEASE do yourself a favor and never give into your curiosity and watch "Pink Flamingos". John Waters is a twisted man, and so are his films. Also, avoid Hostel unless you're into that crap. Dude, I was raised Mormon (still am), and grew up without watching a single R rated film (until I was about your age when I snuck in a neighbor's movie and a library movie, both separate cases. The movies were Black Hawk Down and Deep Rising. My two first R rated films. I kinda regret it though, I felt bad for going behind my parents' backs). I have since watched hundreds, I've gotten the film buff bug, or whatever you wanna call it. Basically, you may just have to wait until you're 17 or 18 or maybe even until you're out of the house. But 17 is the proper and technically legal age to watch R rated films without adult supervision, so when you hit 17 just calmly let them know you're a man now, and you wish to watch anything you want, but that you'll still take their words of caution under consideration. Just be mature about it, and maybe they'll see you're ready for it. When you CAN watch them, here are some great ones to get you started, that aren't hardcore: Equilibrium The Matrix Ip Man The Shawshank Redemption Hot Fuzz V For Vendetta Saving Private Ryan Slumdog Millionaire Shooter The Kingdom The Hurt Locker The Book of Eli

You are 21 and still looking to your parents for permission? Time to be independent and take responsibility for yourself. If you don't want to watch them then don't.

talk with your parents and tell them that you dont like those kind of movies.

just dont watch them

well you fly derp
