A thrilling, yet somewhat absurd action film When an action film offers an interesting premise along with Liam Neeson as the leading man, one expects nothing short of an exciting and enjoyable experience, and Non-Stop does prove satisfying, even if somewhat nonsensical. In large part, the audience is exposed to great levels of unpredictability and very mysterious circumstances, as an air marshal attempts to save his fellow passengers on a trans-Atlantic flight from a terrorist attack. The film is gripping and thrilling throughout, with plenty of tense moments maintaining the feeling of suspense, however it certainly deserved a much more clever final act, rather than concluding as a conventional action film. Although Liam Neeson does again perform well in a leading action role, one cannot help but argue that the rest of the cast, which included such notable names as Julianne Moore, should have been utilized far better. Overall, Non-Stop comes across as an enthralling action film with a rather ludicrous storyline, which is initially well-developed but unfortunately seems to lack a fitting end.
