It seemed to me that whoever directed the Miss Marples with McEwan added some liberal values in the stories, but maybe I’m just one of those paranoid conservatives you always hear about. ;-)
I agree that Ustinov was a terrible Poirot! I enjoyed Rutherford’s movies for her acting, the comedy, and the story line. I tend to view her character as someone other than Miss Marple.
I wasn’t looking for politics so I can’t really say. Sometimes things go right over my head.
