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.

While it doesn't offer any answers, it both thrills and makes you think.

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.

There's a more than satisfactory amount of boom-boom in the movie's trim running time.
