Miss Marple: The Mirror Crack'd from Side to Side

I think on seeing the 1981 Hollywood version and the 1992 version I do feel that being 'British myself that it is much better to keep to the authors way of telling the story as this is Agatha Christies way and that is why she is so popular. As for Joan Hickson playing the part of miss Marple I feel she is perfect and that Agatha Christie was right in her choice and of course she must be right. As to the plots they are meant to be intriguing and complicated not to be made easy to work out .
