Some towns that have curfews have sort of eliminated this prob since kids can't be out past a certain hour, therefore can't be at movies disturbing the rest of us. I do think they should ID everyone (unless they look over 30) to prevent little punk ass 12 year olds from throwing popcorn and giggling during sex scenes. When Titanic came out, I saw it in the theatre w/ my little sister. She's pretty well behaved, but no one else seemed to be. Someone had a "Tickle Me Elmo" shirt that when pressed said "hee hee that tickles!!" Take a wild guess which scene they pressed their shirt
