Super human Liam Neeson kills 35 people, beats the crap out of dozens more, steals cars, causes car crashes, makes a building blow up, and jumps through lots of windows, all to save his daughter, who has been snatched in Paris by Albanian traffickers. It's a lot of fuss over a spoiled, stupid little brat. But of course, it's the old heart rendering father / daughter routine.
That's about it.
Liam Neeson can actually do more than beat up and kill people and wreck cars. Check out _A Walk Among the Tombstones_, 2014. He does some real acting in that one. But he can't resist these action flick paychecks.
