"Non-Stop" is not the clever sort of murder mystery. It is a movie built upon an impossible premise involving a villainous plan that is either the most complicated and brilliant scheme ever concocted, or more likely, the hero is simply insane. The idea is that Bill Marks, a depressed alcoholic air marshal played by Liam Neeson, must stop a would-be hijacking of a plane orchestrated by a villain so devious he must only be the Joker. Every twenty minutes, the unseen criminal demands over an silent series of text messages that he or she must receive $150 million or he or she will murder one person on-board this plan every twenty minutes. However, Bill is the only person receiving the texts, and the account is in his name. Things grow more complicated and absurd from there, as Bill Marks is slowly framed for hijacking the plane, bodies pile up, and the word "terrorist" is thrown around a lot.
Ultimately the Who-Done-It? is hardly worth your time, and worth less of your brain power. Go see "Non-Stop" and then spend about five minutes actually reviewing the events of the film, and you'll realize it was all built upon nothing. There was no brilliant plan, just the illusion of one built by a lazy screenwriter. The Done-It-er is just one of the suspects, it honestly could have been anybody, and being able to guess who depends more upon random luck than sharp viewership. Every action the criminal makes was a fantastic coincidence, often more than impossible, and even then, once the plan is laid bare, it actually makes no sense at all, inevitably collapsing somehow after the criminals were able to impossibly predict every move by the hero for the first hour and a half. But if all you want is to see Liam Neeson shooting people while barking orders at scared passengers, then "Non-Stop" will probably be a mildly satisfying movie. But even after your mild satisfaction concludes: what will you have left? Time wasted on this Earth, gone forever, and only rapidly fading memories of mediocre entertainment.
