Ju-On is probably the scariest movie that I've seen. The traditional horror movies have a lot of gore and horrific scenes. This movie has very little gore in it and cannot be considered as a traditional horror movie.
However, it is very edgy and is very very disturbing to watch.
I think the Exorcism of Emily Rose is the scariest movie I have ever seen. It came out in September of 2005. Movies about demonic possession always terrify me and the fact that this movie is based on real life events makes it even scarier.
I have added a link to the movie trailer and also a link that shows one of the scariest scenes in the movie.
The most scariest movies I have ever seen are The grudge Shutter Darkness fall.
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.
