Horror movies.

[DossarLX ODI]

From what I've seen, many horror movies are usually based off religion or religious beliefs. For example, a person has to be sacrificied to cleanse his or her soul, etc. and then there are massive killings.

Of course, there are exceptions. However, some other horror movies I've seen start with a typical policeman or civilian go to a dark room and spot an altar or a religious sign, then there is a person in the room, you can't see his/her face, and then when you do see the face they are missing eyes or whatever.

Do you guys think that this is necessary? A horror movie is supposed to be surprising and scary, but the fact that the horror is from a religious belief completely derails the movie.
