3 New story ideas for a Thriller

For our coursework we have been researching different thrillers and have come up with three different stories to recreate:

Story number 1: The opening starts of with the camera panning which would then focus on a black silhouette on a hill, the camera zooms in to then reveal a young girl wearing a torn white dress, she looks extremely frightened and shell shocked. She hears a cracking sound and starts running till finally she gets knocked down and the camera switches to her lying on a rock with an arrow on her back. Then a man comes over (we wont see his face) and takes the arrow out her back and through this the audience figures out that this man is the killer.

Story number 2: This opening starts of with two (a boy and a girl) cousins going to there grandmothers house, once they are there they get greeted by their grandmother with a gift the girl gets given a China doll which she is disgusted by and throws it at the wall all the China pieces falling to the floor. At night the Boy can hear the remainders of the doll rattling and feels possessed to go and relive himself of this doll. He does this by going to the churchyard next to his grandmothers house and buries it. The next scene would show an older version of the boy (looking just slightly older) and girl (whose aged massively) going back to their grandmothers house after she's died and the boy remembering that the doll was buried in the churchyard next to it. He goes back to the graveyard and digs it up to reveal that the doll has aged and looks exactly like the girl.

Story number 3: This opening would start of with a girl walking her dog in the park, while running after her dog she stumbles along a small hole in the ground with what looks like a curl poking out of it. She walks over and pulls this girl to reveal that a doll was buried under. She takes the doll out and it looks exactly like her and even has the same clothing on as her, feeling frightened at this point she buries the doll were she found it and carries on walking. She returns the next day to see the hole again with the curl of hair poking out she pulls it out and the dolls clothing has changed to the same clothing she has on. By the end we figure out that she is being watched through the doll.
