so intense and every actor nails it, real life home invasion scenario horror, no violence shown on screen but clearly heard in the background so pretty watchable for those who can't do extreme gore or ghost stuff. extra creepy because it could happen at any time to anyone. it's so surreal and real. probably my favorite horror movie ever and i've seen a lot of horror movies from splatter films to paranormal to experimental to science fiction. this is the best psychological thriller EVER
