There is only one movie that I absolutely will not watch again,
May. I don't know why, but that movie messed me up for days after I saw it, nothing has ever had that effect on me and I have been watching effed up movies and scary movies ever since I was very young.
Jump scares will make me jump and creepy movies will be in my thoughts for the rest of the night, but May made it hard to sleep for a solid week.
