Which Film Ruined It? Let The Right One In How Did It Ruin It? By turning quiet blue waters into what looks like a serial killer's underwater storage tank. A Swedish horror film directed by Tomas Alfredson, Let The Right One In is an ice-cold spin on the vampire tale, immersing its characters among the thick, white canvases of Stockholm. The film tells the story of Oskar and Eli, a young boy and girl with complexions whiter than the Swedish snow, who develop a more-than-unusual friendship. There is something not quite right about Eli. And when she learns of Oskar's constant subjection to humiliation at the hands of school bullies, she believes she can help. After a chilling ninety minutes or so, Let The Right One In comes to a head at the local swimming pool. Oskar's bullies initiate a raid that encourages the remaining children to scatter, and are left alone with Oskar as a result. The fiendish gang then stuff poor Oskar underwater, threatening that he must hold his breath for three minutes. Cue Eli. The swimming pool soon begins to resemble the spilled contents of a Dexter Morgan bin bag, as severed limbs bob gently across the water, It's a scene that's enough to turn your stomach just by looking at another patch of water. Those days of the "relaxing swim" are long, long gone.
