Jumping fairly late on the slasher-movie bandwagon, this stylish but hollow effort from director Manny Coto stars L.A. Law's Larry Drake as the psychopathic Evan Rendell, who fancies himself a misunderstood medical genius. In an inventive opening scene, Rendell performs a bit of impromptu surgery on his keepers at the asylum (who had given him the title nickname due to his fits of nervous laughter) and escapes to his hometown to set up his "practice." This medical mania seems to run in the family, as we are shown in flashback: Evan's daddy once butchered several local women in his search for a replacement heart for his wife, and although he was unable to save her, Pops managed to spirit away young Evan and keep him safe (in a very, very nasty hiding place) before being lynched by the locals. Hiding out in the abandoned family home, "Dr. Giggles" begins a random killing spree in town with his bag of medieval-looking surgical instruments... but he finds new purpose when he sees the medical records of young Jennifer (Holly Marie Combs), who is in line for a heart transplant, and vows to "cure" her himself. This film eschews the possibilities of its demented premise, choosing instead to serve up a flavorless hash of '80s slasher clichés (wisecracking killer, stupid teenage victims, virginal heroine, 20-years-later motif, etc.). The only truly inspired moment occurs in flashback, when we discover the actual hiding place the elder Dr. Rendell chose for his son.
