The ending to Psych 1

Here is my idea on what i think would happen in the rest of Psych 1.

- Jessica is the only survivor from the opening of Psych 1 - I decided to use her in the rest of the film unlike scream where they start with different characters who knew the opening characters, i did this as i want her to be the final girl in my film to conform to the typical horror films.
-Dr Karloff knows that she has seen the death of Laura and now the rest of her friends. The film will follow a scream style story line with the closest friends and family around her being brutally murdered in similar ways to her friends for example having their throat slit and chest stabbed. These deaths are Dr.Karloff's signs that its going to be her soon. As the doctor is trusted at the school nobody believes her when she tries to tell the police that it is him.
As the story builds the loss of her friends and family and the feeling of being alone (as nobody believes her) turns her slightly insane. She knows Dr.Karloff is coming for her but now when or where which adds to her insanity.
The film ends with her staying behind after school for a detention, she is left to walk home alone as she has been outcasted by the rest of her year, what she doesn't know is that Dr.Karloff is following her out of the building, as chase scene begins until she realizes that the main gates are locked. Tension builds as she tries to open it or climb over it when Dr.Karloff comes up behind her and stabs her with the kitchen knife in the back.
