Let me open up by setting the mood for this one. When "Criminally Insane" was first released in the theaters there was a large, industrial sized scale placed in the lobby of selected theaters where it was shown and any woman weighing over 250lbs was admitted to the film for free! This should help set the mood for this poorly filmed, inept but highly entertaining horror-cheapie. The saving grace of this film is the hysterical Priscilla Alden (the 250lbs actress who plays the role of Ethel Janowski). She plays the lead character so dead pan that you cannot help but be entertained by her as she fries a pound of bacon at a time, cooks a dozen eggs, or toasts an entire loaf of bread! Food is actually a character in this film and it is Ethel's worst enemy. She kills 6 people in between stuffing her face with a half-gallon of ice cream, an entire box of vanilla wafers, or a dozen sweet rolls and when she runs out of ideas about how to conceal the bodies...she eats them! Meanwhile she is also the rudest woman you will ever come across, concerned only with her next meal as she spouts anti-semitic statements about her doctor and calls the grocery boy (whom she had just murdered) a "smart-alec kid". So grab yourself a gallon of ice cream and enjoy this 70's horror gem!
