A lot of perfectly good film show their cards early, establish a unique premise and let the audience explore a topic at a leisurely pace, without much in terms of surprise. this film is not one of those films.

I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.

One of the worst ways to make a cult movie is to set out to make a cult movie.

The film never slows down or bores, plunging from one harrowing sequence to the next.
