My mum never let me watch scary or violent movies when I was a kid (I remember her telling me that I could wait until I was older to watch The Terminator and that I'd appreciate it more when I was older anyway). The first violent movie she let me watch was when Aliens was showed on free-to-air TV. I think I was about 12 at the time.

My dad's girlfriend, on the other hand, tells me that her mother used to drag her to violent horror movies when she was little because her mother couldn't watch them alone.
