“What’s the difference between love and obsession?”So croons Archie Madekwe’s glamorous pop star Oliver, sung with a dead-eyed stoicism as he stares directly at the camera — demanding the answer from his fans, the industry, or maybe us, the audience. But his machinations soon take a sinister turn, morphing Lurker from the social-media riff of Almost Famous into a startlingly fresh and twisty new-age take on The Talented Mr. Ripley. One day, that star, Oliver, suddenly rolls into the store with his entourage. Feigning ignorance about who Oliver is, Matthew captures Oliver’s attention and earns an invite to his house the next day. It’s a sympathetic portrayal that makes Matthew’s sudden sinister turn feel like a genuine rug-pull.
