Heard the one about the kid sent mad by his father's surgical obsessions, who escapes from an asylum years later to wreak vengeance in his home town? Of course you have. Ultra-derivative slashers such as this medical Halloween rip-off appeared to be the last gasps of old-school splatter, until the genre's recent resurgence with the Scream and I Know What You Did Last Summer franchises. From the “practical joke that goes wrong” to the final line-up of disembowelled victims in the sadistic surgeon's waiting room, there isn't one iota of originality on display in this comatose collection of “Dr Kill-Dare” cliché casualties.
