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.

After playing with our expectations, this turns out to be a very different sort of film.

what a terribly boring film. I'm sorry but this is absolutely not deserving of best picture and will be forgotten quickly. Entertaining and engaging cinema? No. Nothing performances with flat faces and mistaking silence for subtlety.
