Simple and well acted, it has tension enough to knot the stomach.

All that we are seeing on the screen is happening with real people, real action sequences in the background, forcing the eye to watch as if we were there.

The movie's not perfect, but it sticks the landing of its message. It was engaging - thrilling at times - and I personally thought it was a great time.

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