Superb film

Rating: 10/10 (1 January 2019)

I have read many comments regarding a loose end. I think it all goes every thing in really well. The whole point was not knowing what it was that turned them suicidal.
The film is intense at times and thought you get to see what happened to the people you meet at the start. The ending is one that proves the ones with the stronger will survive.
It leaves foe the viewing to imagine what the element in play was.
