I really enjoyed the first hour of this. I couldn't tell where it was going to lead, and was fully engaged with the characters. I thought Sophie Turner was excellent. The last 20 minutes however ruined an otherwise good movie. The whole premise that this teenage girl could somehow track down the prison guards that assisted in her fathers' execution, seems incredibly far-fetched. To then have the resources to travel around the country killing them one by one and getting away with it is a stretch too far.
