SERIES PREMIERE: Netflix continues to roll out new series with the indiscriminate onslaught of an avalanche – and today, in addition to unveiling Disenchantment (which I’ve previewed separately) and To All the Boys I’ve Loved Before (which I haven’t), the streaming service presents the U.S. premiere of this imported Polish crime series from 2017. It stars Marta Nieradkiewicz as Ola, a young woman who returns to Lodz from London, witnesses a violent accident that may be murder, and falls in with a small band of tech-savvy amateur sleuths who call themselves the Violets. (This Ultraviolet is not associated with the 2006 Milla Jovovich sci-fi film.) What makes this subtitled entry noteworthy is that it’s fairly polished (not just Polish), and I’m a big supporter of anything that brings us TV from other countries and cultures.
