The phenomenal Dale Dickey elevates a fairly generic Canadian OAP revenge movie, covering similar thematic territory to the Rosamund Pike-starring drama I Care a Lot. Dickey, whose sandpaper growl of a voice has never been put to better use, plays Ann (aka The G, for Granny), an elderly woman who is targeted by crooked, state-appointed legal guardians. Ann and her seriously ill husband are removed from their home and locked in a residential home, while her slippery legal guardian digs into her savings. But Ann is not the helpless little old lady that he thinks she is. She’s bullet-hard, knows her way around a variety of firearms and has an assortment of seriously dangerous people on speed dial. Enjoyably pulpy stuff.
