Although this 2014 thriller has its fair share of violence and gross images, that's not what makes it so disturbing. Jake Gyllenhaal stars as LA thief Louis Bloom, who discovers a lucrative new career as a cameraman covering the city's grisliest crimes. His nonstop hunt to get the "money shot" gets more and more ruthless, which is why one Redditor said the film is "seared into my brain."
