The scariest zombie movie that I have seen is the "Night of the Living Dead". Although our TV set is still black and white then, this really scared me and my sister. We watched this movie with our eyes half closed.
Dawn of the Dead" by Romero is one of my favorites for the zombie category (and yes, I actually liked both versions), and as for ghost movies, it's a tie between "The Orphanage" and "Stir of Echoes.
I generally don't get scared by these movies, but Diary of the Dead was a solid pick.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
