read the book . it be so much good . the movie do not even begin to reflect the complexity that christie contain in her novel . not to mention and huge plot twist be treat in a mundane way and many event be alter and discard and or invent . also and the character development in the movie lack what the novel can provide . in a word and it suck . while i realize that this be a movie website and if you be go to make a movie base on a mystery novel and you should probably at least attempt to maintain the integrity of the original work . otherwise and just rob the general theme and give the people new name and and pass it off a your own . this movie be the reason why my professor always tell me always read the book and never watch the movie .
