Your missing out! Allot of scary movies mirror realism in everyday life. Not that it's good/ethically moral etc, but It happens. If you go through life utterly sheltered from real life, you could end up in some kind of fantasy land. Wait till your 18 and then discover how messed up this earth can be..
I wanted to see some ba<x>sed on the trailer. I found out that none was good enough. Your parents are right. It's not worth yr times.
I can't even watch the trailers on the tv. I change the channel quickly and don't return until I am sure the trailer is finished.
At least now I know I am not alone :) When my son wanted to see a horror movie I had to get a family friend to go with him.
