As entertaining as Liam Neeson's many action thrillers are, they very rarely cross the boundary from being an "action flick" into the pretentious label of "cinema." But one Liam Neeson thriller was so good that it has become a certified cult classic, and completely "stunned" beloved critic Roger Ebert in the process. Released in 2011, Joe Carnahan and Liam Neeson's film sets itself up as another turn-your-brain-off thriller. But it quickly descends into something much more. 15 years later, it's heading to free streaming to stun even more people.
