Non stop thriller with its own flaws

Rating: 9/10 (3 March 2014)

It was the ideal film for me to watch today noon at cinemax, with nothing to do on a visit to a megacity with bro. Liam Neeson's films seem to be typical...this one follows the lines of Taken in a slightly similar fashion. A not-so-happy cop or ex cop, tall and charming and elegant but divorced with kids issues taking on some bad guys who want to harm him and others. Soon comes in thrill and speed, kicking and fighting, bam bam and boom boom, and well I'm not gonna spoil anything more.
The typical cop, an ex FBI guy, now an air marshal, is caught in a dilemma 35000 feet above when someone threatens him on board mid air by sms to kill passenger after passenger if he does not get him 150 million dollars transferred to an account. The cop has no option but to find out who is trying to terrorize everyone, but is in for surprises he would not be expecting.
Concept? Great...similar to Taken, like I said before, but definitely an unconventional film. It's not a typical hijack movie that you have seen before but it nevertheless keeps you hooked on.
Liam plays his stereotyped role quite well, all others have done their best too. 90% of the film is shot on an aircraft, with realistic effects. Movie never drags, and is fast paced.
Some stuff is not well explained, as you will know when you reach the end.
Enjoy!
