High tension thriller movie.
It is interesting but not really hitting the head of the nail, in my opinion.
*SPOILER ALERT*
It is based on actual events, which obviously restricts the creative freedom, but I would have loved to see a completely non-violent ending.
Mark Strong does a good job. He is tasked with a difficult role, as he needs to portray a lot of emotions while talking on the phone.
It was great fun to see the SAS team go through several exercised while preparing for an operation.
All in all an ok movie, but not really great.
