Teenager Megan Gordon (Rainbow Harvest) styles herself after Winona Ryder in Beetlejuice, which makes her a laughing stock at her new school, which is populated exclusively by preppy types. Nikki Chandler (Kristin Dattilo), candidate for school president, befriends Megan, but doesn't realise the danger she is putting herself in by doing so, for Megan is being controlled by the demonic force that resides behind the glass of the antique mirror in her bedroom.
While not particularly original, the idea of mirrors as portals for evil having existed for centuries, Mirror Mirror proves to be an entertaining piece of early '90s horror thanks to strong performances from a decent cast, solid direction by first-time director Marina Sargenti, and several memorable set-pieces, including a blistering shower scene.
As Megan is slowly seduced by the malevolent being on the other side of her mirror, she sets about evening the score with her tormentors, which means giving school bully Charleen (drop-dead-gorgeous Charlie Spradling) a nose bleed in the cafeteria, causing science teacher Mr. Anderson (Stephen Tobolowsky) to have a seizure, and scaring nosy house clearance lady Emelin (Yvonne De Carlo) away from her prized possession.
Eventually, Megan's power spirals out of control, resulting in death: when Charleen's boyfriend Jeff (Tom Bresnahan) spurns her affection, Megan feeds him to the demon; Emelin is impaled by a shard of glass; Megan's mother Susan (played by horror icon Karen Black) has her arm mangled by the waste disposal; and Nikki's boyfriend Ron (Ricky Paull Goldin) is killed by an evil doppelganger of his girlfriend. Best of all is Charleen's death while taking the aforementioned shower: a totally naked Spradling (so hot that she even out-scorched Sherilyn Fenn in Meridian) is scalded all over by jets of steam.
All of this is so much fun that it's easy to forgive the slightly overlong runtime, the rather confusing ending, and William Sanderson's limp ponytail.
