Scaly Old Lady Steals Brains from Ditsy Bimbos!!
29 April 1999 | by (Mooport Moos, VA) – See all my reviews

There's nothing atomic about this brain-less brain movie, although it is a monstrosity. In which a decrepit old hag connives with yet another mad doctor to transplant her evil, shrewish brain into the young, nubile bodies of several dimwitted housekeepers. You know the doctor is a demented mad genius because his lab contains a lot of flashing lights, a table, and a hot tub chamber. The three nubiles are innocent to the point of stupidity: when one of them receives the brain of a cat, its actually an improvement. Another sports the worst Old London accent that I've heard since Crater Lake Monster. The irritating voice-over narration leads the audience through the movie by the nose like some sick, deviant tour guide. You'll chuckle at the shaggy-faced "mistake" slavering in the shrubbery, waiting to pounce on the first lovely to take an evening constitutional, but such moments are fleeting. It is disturbing and depressing to watch the old hag ogle and rapaciously paw her young captives, who don't even bother to put up much resistance. This dreary little slug of a movie cannot even be redeemed by the MST3K 'bots; MooCow says this bungled brain-drain of a film is for serious schlock-hounds only! :=8/
