a good crime novel might be material for a fine movie or even for some entertaining distraction and a the hunt for the killer be a plot technique that keep the attention focus . how they make such a gruesome movie out of an agatha christie novel be an art in itself . a not have read the novel and i be not sure if the plotting mistake be due to the writing or the adaption and but either way and they be there and aren not go away . the poison in the pill that the major never take . why would he take one now . the killer not try to hush the possible poisoning but even inform the police about it . the exhumation base on the fact that a pill bottle be in his bathroom that wasn not there before . the hotel nurse tell someone in a highly suspecting way that she saw the killer . why not tell the police or even her new friend miss marple . dramatic effect like the exhumation during the night and some tiny voodoo and the nervy score can not save the lack of drama . badly script and awfully act and barbados seem a perpetually overcast island with some techno echo cricket chirp away every time we be suppose to witness outdoor scene at night . this isn not even entertain anymore and this movie be a crime itself .
