“Cinderella’s Curse” (*1/2 out of four) was a disconcertingly awful “remake” of the 1950 Disney tale about Cinderella (Kelly Rian Sanson) who summons the help of her fairy Godmother (Chrissie Wunna) to enact bloodthirsty revenge against her stepmother Danielle Scott) and her vicious sisters (Lauren Budd and Natasha Tosini). Hard to believe that this could be made after the similarly titled (and similarly terrible) “Cinderella’s Revenge” which was just released last month (!) but no one ever accused horror filmmakers of too much originality. Like that film, this one is mean-spirited and gruesome and as needless as a glass slipper.
