Netflix’s eight-part British horror series Red Rose is presented as increasingly unsettling because its threat comes from familiar technology rather than supernatural creatures. Set near Manchester, it follows recent school-leavers whose lives are disrupted by a malicious smartphone app, highlighting anxieties around social media, surveillance and growing up online.

The app initially appears as a spam-like text message from a familiar-looking number, but gains control over users who follow its link. After Rochelle, played by Isis Hainsworth, dies by suicide while under its influence, her friend Wren, played by Amelia Clarkson, downloads the app to investigate; the series was produced by Eleven and has a 100% Rotten Tomatoes score.
