Ghastly, trashy, raw, and grisly, this Chilean film is in the neo-grindhouse tradition. Unlike some of its modern ilk, it doesn't have much humor, going instead for offensiveness and controversy. It may not be in any way literate, but it never tries to be, and what it tries to do it does quite well. The pace is very energetic and the action/horror and suspense/terror beats are fantastically done. Grand finale, too.
