PiITIFUL--Set in 1954 - wtittenby someone who knows nothing about Agatha Christie' or the era. I've nothing against swearing, but to put this in a 1950's period piece,is completely ridiculous. I was just waiting for a punk to appear and rap to be played in the background. I feel very very sorry that these excellent actors were put through this ordeal. Formulaic- you bet your life it is . The Telegraph gave it 4 stars and the Guardian 5 stars . Presumably out of 5 ???????. To prove I'm very comfortable with swearing --it's SHIT.
