If the story of the “Last Sentinel” was the basis for an episode of television, it could work, dealing with a short run time and more focus on achieving a certain level of suspense with fewer dramatic moves. However, this is not T.V., but a movie from writer Malachi Smyth and director Tanel Toom, and they’re not in a hurry to generate any sort of nail-biting viewing experience with an endeavor that inexplicably runs for nearly two hours. The material has some ambition to detail the habitual cycles of destruction found in humanity, and there’s some interest in replicating a chain-of-command thriller, where duty and survival are forced to battle it out. “Last Sentinel” is a confusing picture, showing no interest in screen movement despite taking on a plot that has the potential for a more active sense of danger, leaving the audience with very little to rile up the senses as one comatose scene after another fills up a painfully overlong run time.
