Excellent script writing and action scenes . Hercule Poirot is potrayed really well in this adaptation than in the 1974 version. The the flashback scenes make the motive very clear and film has an excellent ending . In the 1974 movie , ending wasn't clear , but in this version its very clear. The majestic luxury of orient express and route it took is well shown. Expects another great movie version of Agatha Christie with Kenneth Branagh as Hercule Poirot.
