F3lixL3g1ons’s review published on Letterboxd:
Why has nobody done this before! After all, Pinochet's pedophile torture cult makes the Manson family look like The Muppets. Underground fans may find Colonia offensive, 'cos it's all clean and mainstream: it doesn't deliver tons of violence we have seen a million times with cult films. In fact, it plays more like an intense psycho drama. But that doesn't turn me off at all. My only complaint: Colonia dismisses the infamous, nerve-frying Nazi background and all. Still, an above-average crowdpleaser — and one that commands respect!
