Can a 12 year old watch a 15 film with an adult?

Yeah, as long as it's a responsible adult, like family... If it is a Horror movie, make sure to sit with the adult and turn it off if you get too scared... I'm 12 and right this minute, i'm watching a horror movie called pandorum... It's rated 15, but i cover my eyes :) Anyway, I say yes :) Check the back of the DVD case, or read reviews to check if it is the right movie for you :)
