Slasher film research

I have researched a couple slasher films to find the best techniques to make a film connect effectively with the audience.

Saw
The film saw connects with the audience by telling a background story behind the main character, this make touches this audience making them want the character to survive and by feeling the emotional pain of the main character when one of his/loved ones has died. The saw films all use dark lighting in almost every scene to show negativity to link with the killing and gore. Saw also has a very clever traps and torture techniques that are explained well to the audience that may interest people that like that sort of thing

Friday the 13th (remake)
The friday the 13th remake used younger adolescent characters so the audience can connect with as they have so much in their lives to live for. Teenagers can have less courage than adults and can make dumb decisions which also help to connect with the audience giving them less hope for the characters survival.

Nightmare on elm street 
This film uses a very interesting way of killing characters as they are killed in their dreams. This makes the characters seem more vulnerable as a dream is a fantasy world meaning anything can happen. The idea of Freddie being in a dream scares the audience which could keep them awake at night. This is a very clever idea but could have not been accomplished without the menacing characteristics of Freddie Kruger himself.
