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

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.

The movie is made so realistic it has a lot of that WoW feeling at the right moments and never tooo over the top. the suspense is done so well and the emotion is felt. Very well put together with the music and all.

One of the most extraordinary films you will see this year. Take that as you want.
