First, let's talk about the 'Inspired by a True Story'. It is something that I wish the movie industry would monitor. The simple fact is that just about anything could be based or inspired by a true story. The Brady Bunch could be based on a true story because somewhere out there (many places), somebody with children married somebody else with children.
Jaws was based on a True Story. So, was Shawshank Redemption, A Few Good Men, etc. etc. Only the degree to which these movies are based on a true story varies.
Regarding the movie, it was somewhat intriguing. I cannot say that I not found myself waiting for it to end, which means I liked it somewhat. I was kind of similar to the original 'Taken' with Liam Neison.
The factor I disliked the most was its political correctness. Some people may debate this, but you have a bad ass girl going into a foreign country (Russia, no less) and for the most part dictating to their police force how things were going to go down. I think it was part of the movies' message that thousands of women are trafficked every year, and "we are going to show the world that not only is that wrong, but we will also show them just how tough women can be."
It is certainly tragic what goes on with trafficking. I do not need to reminded through political innuendo that guys are the culprits (we all know that). The message of 'don't mess with women' was too much over the top.
