An inferior attempt to make an American version of Miss Marple combined with slap-stick comedy that made The Three Stooges look sophisticated. What did poor Helen Hays do to end up in this gawd-awful drek?
One of the worst offenders, by far, is the character of their chauffeur and minder--a retired bead cop who sounds like he came out of central casting in the 1920s--who was hired by their sisters' nephew to keep them out of trouble. He lectures them multiple times to be good little girls and to do what he says--like they're naughty little children rather than competent adults. If he had been competent as a cop, I could almost forgive him. Instead, he's one of the primary slap-stick offenders.
Of course, women can't drive, especially not elderly women. This "Joke" is slapped into the audience's face multiple times.
Really, I cannot imaging why anyone would think this was a worthwhile effort. The writers and director should have been ashamed.
