Netflix’s A Toxic Love Story is one of those true-crime docs where every time you think you’ve figured out who the victim is, it flips on you. Without giving away the turns, it centers on a newlywed US marshal, his new wife, and his ex-fiancée — and a campaign of threatening messages and a Craigslist scheme that spirals into a full-blown revenge plot. Director Alexandra Lacey structures it so you get information in the same order investigators and the public did, which means you’ll form a theory and then watch it fall apart. It’s twisty and genuinely unsettling. If you want a true-crime doc that keeps you off balance the whole way through, this one’s streaming on Netflix now.
