This movie tries to be many things; its mostly an action film but also plays heavily into the family drama while throwing in some dark comedy too, all with mixed results.
The somewhat recycled story follows Kevin Costner as a gruff ex secret service agent who after being told has just 3 months to live sets out on that infamous "one last mission" in exchange for an experimental drug that will save his life. This last job just happens to take place with he also tasked with looking after his estranged teenage daughter (Hailee Steinfeld) after his ex wife (conveniently) has to leave town.
The action storyline is quite good though thanks to Luc Besson; decent stunts, tons of broken glass and bullet riddled bodies, and Costner gets the job done -Liam Neeson style-. The ending sequence was also refreshing as all along I had been assuming a cliché kidnapping, so nice twist there.
I did find the amount of perfect English being spoken and understood in France and especially Serbia a little convenient but whatever, this was mindless but still worth a watch.
