OMG please help. This is driving me insane. So, back in like 2009-2010 I saw a movie. It was a scary movie, I THINK it was in 3D... I'm not entirely sure. It was about this guy who kills people (I know, super descriptive), but then the killings stop for like a bunch of years. Then they start happening again. There's a group of high school kids and they start dying and then at the end it ends up being one of the high school kids and his father was like the murderer before. I KNOW IT'S REAL I JUST CAN'T REMEMBER PLEASE HELP.
