This was a compelling take on loss. Your use of repetition is bold, especially given the word limit, and I found it very effective. There's a chilling atmosphere throughout, and it lasts until the final word. Nicely done!
This might've just been my interpretation, but it seems like the sister was murdered in front of the narrator's eyes.
Nope- I could follow the plot pretty well.
I'm impressed with how you tackled such a complicated subject in so few words. I truly felt the narrator's loss, and the phrase "horror film" added an element of terror.
I would maybe title your story with something like "On Repeat".
