detective sergent vince de carlo ( james luisi ) and company be on the case of a vicious serial killer or rapist . can psychologist carol ( susan sullivan ) help and or will she become the killer next victim . and what be with the killer hilarious white dude afro . inspire by the case of serial killer ted bundy and killer delight aka the dark ride be a rather dull serial killer tale from 1978 that doesn not offer much . if anything and it more of a police procedural flick than a horror movie and as much of the violence occur off camera . sure and we get mutilate body and but we do not get a whole lot in the exploitation department especially consider that they be from the aftermath and and not during the crime . those hop for the like of the toolbox murder or maniac will be very disappointed . fortunately and there be an impressive scene involve a woman try to escape the killer that get the tone right and and be quite suspenseful to boot . also and john karlen be quite effective a the killer and though his hilarious hairstyle ( white guy with afro be always worth a chuckle ) be more than a bit distract . the dark ride be too routine and mediocre to really warrant a recommendation and a it lack the proper exploitation element and and be date even by the standard of the time . those look for a good example should probably turn to don not go in the house and a few others instead and a this just doesn not cut it .
