The TV show Supernatural, which has two brothers fighting demons and monsters every week is sometimes very brutal.
My 14 year old son loves watching it though the rating is MA15 because of the violence.
Do other under 15 year old's watch it or is it too violent for them to watch?

#horror I'm 20 and I still don't like watching Supernatural. Not just the violence, but the first season in particular is actually quite spooky. Makes me scared of the dark, no idea what it would do to more impressionable younger minds. I wouldn't let my kids watch it until they were over 15 for sure.
