“Mission Impossible: Dead Reckoning- Part One” (** out of four) was a feeble sequel about Ethan Hunt (Tom Cruise) and his IMF team (Simon Pegg, Ving Rhames, Haley Atwell) who have to track down a dangerous weapon after it has fallen into the hands of a worldwide terrorist (Esai Morales) and could result in global warfare. Kudos for bringing back Henry Czerny from the original and other various “Mission Impossible” actors from previous entries but this seventh entry is one of the weakest with a stilted script and severe overlength at nearly three hours. Even the climax aboard a train only serves to hark back memories of the classic original. Only some spectacular stunts (some performed by Cruise himself) keep it alive.
