I just downloaded it and watched it without reading what it was about. Didn't have high expectations and it turned out to be probably my favourite movie of this year. It's a bit long but there's only like 2-3 scenes I could see cutting. Don't want to give details to spoil it though.
The news is getting pretty crazy lately with the number of people being held in captivity. Jesus, 30 years for 3 people in the UK!
